SSL VPN and Dynamic DNS - ddns on IOS

Hello,
I'm trying to configure a SSL VPN tunnel via SDM on a 877 Router. The router gets the public IP address dynamically from the ISP, so I have configured the DDNS to access remotely to the router. I would like to know if it's possible to configure the SSL VPN to support the dynamic IP via SDM o CLI.
Regards
Gerard

Seems like i have fixed the problem using:
webvpn gateway gateway_1
ip interface Dialer0 port 443
ssl trustpoint local
inservice
However when the router is rebooted, it results in this error:
Invalid ip address First configure an IP address for the gateway
Any idea how to delay the webvpn commands at startup until dialer0 gets a dynamic IP ?

Cisco 1841 SSL VPN and Anyconnect Help

I am pretty new to Cisco programming and am trying to get an SSL VPN set up for remote access using a web browser and using Anyconnect version 3.1.04509. If I try to connect via a web browser I get an error telling me the security certificate is not secure. If I try to connect via Anyconnect I get an error saying "Untrusted VPN Server Blocked." If I change the Anyconnect settings to allow connections to untrusted servers, I get two errors that say"Certificate does not match the server name" and "Certificate is malformed." Below is the running config in the router at this time. There is another Site-to-Site VPN tunnel that is up and working properly on this device. Any help would be greatly appreciated. Thanks

Perhaps you have changed the host-/domainname after the certificate was created?
I'd generate a new one ...

Ssl vpn and soft phone

Does the ASA or IOS support an SSL VPN that includes the Cisco softphone like it does say RDP, SSH, etc? I'm trying to determine if I can have a user connect a soft phone to our parent company's SSL VPN so they can use their Cisco phone system, while simultaneously having a remote access vpn tunnel to our division's data network. In short, our employees need to use phones that don't exist on our network while having access to our data network. I've been able to test having an SSL vpn session open at the same time as an IPSec remote access session, but the softphone is not an option in my current code of 8.4 on the ASA. I thought I heard it might be available in 9.0. It seems like it would work in reverse, i.e. having my users connect to my SSL VPN to use my data network and then IPSec to our parent company for the client's locally installed soft phone, but that's not an option for me. The link below seems to suggest it's possible in IOS at least, but I haven't been able to find any details beyond the sales pitch it offers.

Clientless SSL VPN and ActiveX question

Hey All,
First post for me here, so be gentle. I'll try to be as detailed as possible.
With the vast majority of my customers, I am able to configure an IPSEC L2L VPN, and narrow the traffic down to a very minimal set of ports. However, I have a customer that does not want to allow a L2L VPN tunnel between their remote site, and their NOC center. I thought this might be a good opportunity to get a clientless (they don't want to have to launch and log into a separate client) SSL VPN session setup. Ultimately, this will be 8 individual sites, so setting up SSL VPN's at each site would be cost prohibitive from a licensing perspective. My focus has been on using my 5510 (v8.2(5)) at my corp site as the centralized portal entrance, and creating bookmarks to each of the other respective sites, since I already have existing IPSEC VPN's via ASA5505, (same rev as the 5510 )setup with each of the sites.
First issue I've run into is that I can only access bookmarks that point to the external address for the remote web-server (the site has a static entry mapping an external address to the internal address of the web server). I am unable to browse (via bookmark) to the internal address of the remote web server. Through my browser at the office, I can access the internal address fine, just not through the SSL VPN portal. I am testing this external connectivity using a cell card to be able to simulate outside access. Is accessing the external IP address by design, or do I have something hosed?
Second issue I face is when I access the external address through the bookmark, I am ultimately able to log onto my remote website, and do normal browsing and javascript-type functions. I am not able to use controls that require my company's ActiveX controls (video, primarily). I did enable ActiveX relay, and that did allow the browser to start prompting me to install the controls as expected, but that still didn't allow the video stream through. The stream only runs at about 5 fps, so it's not an intense stream.
I have researched hairpinning for this situation, and "believe" that I have the NAT properly defined - even going as far as doing an ANY ANY, just for testing purposes to no avail. I do see a decent number of "no translates" from a show nat:
match ip inside any outside any
NAT exempt
translate_hits = 8915, untranslate_hits = 6574

As you can see, I have things reasonably wide open - with no port restrictions on this one yet - this is for troubleshooting purposes, and it will get restrictive as soon as I figure this out Right now, the ASA5510 is pretty restrictive, and to be brutally honest, I'm not certain I'm even using the packet tracer 100% proper to be able to simulate coming from the outside of the network through my ASA5510, out to a remote ASA5505, and to a web server behind that 5505. I'm sure that the issue is probably going to be a mix of ACL's between the 5510, and the 5505.
I guess the main question, is Clientless SSL VPN really a good choice for this, or are there other real alternatives - especially since my client doesn't want to have to install, or use an actual client (like AnyConnect), nor do they want to have an always-on IPSEC VPN. Am I going about this the right way? Anyone have any suggestions, or do I have my config royally hosed?
Thanks much for any and all ideas!

Hey All, I appreciate all of the views on this post. I would appreciate any input - even if you think it might be far-fetched. I'm grasping at straws, and am super-hesitant to tell my customer this is even remotely possible if I can't have a POC myself. Thanks, in advance!!

Anyconnect ssl vpn and acl

Hi Everyone,
I was testing few things at my home lab.
PC---running ssl vpn------------sw------router------------ISP--------------ASA(ssl anyconnect)
anyconnect ssl is working fine and i am also able to access internet.
I am using full tunnel
i have acl on outside interface of ASA
1
True
any
any
ip
Deny
0
Default
i know that ACL is used for traffic passing via ASA.
I need to understand the traffic flow for access to internet via ssl vpn.?
Regards
MAhesh

As you say correctly, the interface-ACL is not important for that as the VPN-traffic is not inspected by that ACL. At least not by default.
You can control the traffic with a different ACL that gets applied to the group-policy with the "vpn-filter" command. And of course you need a NAT-rule that translates your traffic when flowing to the internet. That rule has to work on the interface-pair (outside,outside).

SSL VPN and dedicated IP address

Hello
I have an ASA 5505 8.3 and i setup it with ADSL 6.3
I am trying to dedicate IP addresses to clientless SSL VPN user: is it possible ?
If not is it possible with Anyconnect client ?
If yes i can't perform it !
I have a user test and i want dedicated him an IP address . After authentification user can connect to a web application but when i see the netstat, it is the IP adress of the ASA which is connected ...
Could you help me ?
Regards
L.Malandain

Two ways -
Frist create pool with one IP address and assign that to group policy.
Second- modify the user atributes-
username test password xxxxx
username test attributes
vpn-framed-ip-address
Thanks

FIOS and Dynamic DNS

I'm thinking about switching from Verizon DSL to FIOS, but I have a few concerns.
Right now I am able to directly connect form my linux-based router to the DSL modem via PPPoE. If for some resaon the PPP link drops the router just re-establishes it, and it always knows my outside IP. It can also update my multiple dyanamic DNS addresses automatically when this happens. My DSL IP address seems to change only when I shut down my router - it lasts weeks at a time.
With FIOS it sounds like you are forced to use NAT with the supplied router. I can go ahead and disable wireless on it, and then just set up my own router to use a static IP and put it in the DMZ to get as close to a bypass as I can. However, if my outside IP changes my internal router isn't going to know about it, and won't be able to update my dynamic DNS/etc. It looks like the FIOS routers will update dynamic DNS addresses, but I'm not sure if they support namecheap, and I also don't know if they support updating more than one dynamic DNS service when my IP changes.
It also sounds like they cut the copper connection, so if it doesn't work out right it will be very hard to go back to DSL.
Does anybody know:
1. Will the supplied router update more than one dynamic DNS service automatically?
2. Will the supplied router update a namecheap hosted dynamic DNS record?
3. When updating a namecheap DNS record will it only touch the A record and not mess with all my other DNS settings?
4. Can I somehow configure the router to provide my external IP to a single internal computer via DHCP (ie router gets an address from verizon, and then the router offers that address to my own router)? Obviously this won't work with more than one computer on the router.
5. Can I alternatively connect to the verizon-provided router using PPPoE or a similar protocol to just get my external IP directly tunneled through the router?
6. Does a FIOS TV standard definition tuner box require a network connection?
7. What happens if the tuner it isn't connected to the network? I won't be using any kind of interactive services anyway since the tuners will just be connected to my DVR.
8. Does the network connection have to be on the same subnet as the verizon-provided router, or is it sufficient that it be able to reach that router or the internet via NAT (there would be a NAT layer between my internal network and the verizon-powered router)?
9. If this stuff doesn't end up working right, can I just pull the plug on FIOS and go back to Verizon DSL and POTS?
In case it isn't clear, here is how I envision the network looking:
Verizon - Verizon Router - NAT with My Router in the DMZ - My Router - NAT - My internal network
I guess if I get really desperate I could try to find a tunnel broker of some kind - not sure if anybody does that for IPv4 the way it is done for IPv6. That would allow me to get my external IP through the NAT and potentially give me a static one as well...
I REALLY don't want to pay an extra $50 for a static IP. I'd probably just stick with the DSL if it came to that even though it is actually more expensive than switching (for dynamic service) and it is a lot slower...
Solved!
Go to Solution.

Hmm - that idea might not actually work out all that well. It might or might not work at all, but one thing that it would probably do is make it impossible to access the router's web interface (since the router wouldn't have an IP address of its own on any of the ports). So, if it did work it would be a once-and-done configuration and then I'd need to reset it to do anything else with it. This would also make it impossible to attach set-top-boxes directly to the actiontec router, but then again they'd be only one NAT layer away from verizon if I attached them to my home network.
I suspect I might be better off with the DMZ approach and just living with a single dynamic dns entry. The main reason I use more than one of those is so that if my IP address changes I don't have to wait for the DNS TTL to run out to find out what the new IP is - I can just wait a few minutes to be safe and resolve one of my other dynamic addresses which won't be cached anywhere so it will get the fresh entry.
I guess my other option is to fire up nslookup and point it directly at the appropriate DNS server so that I"m not seeing a cached response.
I've heard mixed reports on how often the FIOS IPs change anyway. If they only change once in a blue moon I'm not terribly concerned about this stuff.
(Why can't everybody just switch to IPv6 and end all this NAT nonsense anyway...?)

OS X 10.6.1: bootpd, named, and dynamic DNS zone updates

I have OS X 10.6.1 installed on a Mac Pro. It is configured to be the name server and DHCP server for my home network, i.e. /etc/named.conf and /etc/bootpd.plist have been modified to provide these services.
I've encountered no problems with either the name server or the DHCP component of bootpd after upgrading to OS X 10.6(.1); however, one thing that continues to bug me is how to configure bootpd to dynamically update the DNS zone files whenever a lease is issued, released, or expires.
At work, I use the Internet System Consortium's DHCP software and have it configured to dynamically update DNS whenever leases change state. I would really like to have DNS done the same way at home.
What changes need to be made to /etc/bootpd.plist that would allow dynamic DNS updates to occur?

Did you ever get an answer to this? Would rather not change the DHCP server in Snow Leopard....
Thanks

IP Phone SSL VPN and Split tunneling

Hi Team,
I went throught the following document which is very useful:
https://supportforums.cisco.com/docs/DOC-9124
The only things i'm not sure about split-tunneling point:
Group-policy must not be configured with split tunnel or split exclude. Only tunnel all is the supported tunneling policy
I could see many implementation when they used split-tunneling, like one of my customer:
group-policy GroupPolicy1 internal
group-policy GroupPolicy1 attributes
banner value This system is only for Authorized users.
dns-server value 10.64.10.13 10.64.10.14

access-list split-tunnel remark split-tunnel network list
access-list split-tunnel standard permit 10.0.0.0 255.0.0.0
It is working for them w/o any issue.
My question would be
- is the limitation about split-tunneling still valid? If yes, why it is not recommended?
Thanks!

Hi,
If you're not using certificates in client authentication then the SSL handshake will complete before the user is requested to authenticate with username/password. If this authentication request fails you will see the SSL session terminated immediately following this failure (as in the logs you provided). Notice the 5 seconds between the SSL session establishment and termination, this is most likely when the user is being authenticated against the aaa server. If the phone is failing authentication against an external aaa-server you'll want to investigate the logs on that server to determine the root cause of the failure. The ASA can also provide confirmation of the authentication request/reject with the command 'show aaa-server'. If you want to see what's going on at an authentication protocol level you can enable several debugs including "debug aaa authentication|common|internal' and protocol specific debugs such as 'debug radius user|session|all' or 'debug ldap'.
Did this answer your question? If so, please mark it Answered!

VPN and Split-DNS problem connecting 851 to 3030 Concentrator

I have configured a Cisco 851 (IOS 12.4(11)T) to connect to the Cisco 3000 Concentrator (v4.72G). I am having multiple problems:
1. On the concentrator I have specified multiple domain names for split DNS "hq.portablesunlimited.com,hq.cellfonestore.com". However I see only the first name created for the dns views.
2. We have a static WAN IP address with a fixed DNS Server name given by our ISP. I am using the same DNS name on the client PCs connected to the 851. I am able to resolve any external names for e.g. "www.google.com". When I try to resolve a DNS address (Split-DNS) for e.g. server.hq.portablesunlimited.com, it fails to resolve the address. I tried to specify the address of 815 (10.0.0.1) as the DNS server for the clients, in this case the clients do not resolve any address. However if I go to the 851 console and ping say "www.yahoo.com" it works and then I can resolve that address "www.yahoo.com" from the client PCs also.
I don't have any firewall or NAT enabled on the 851.

AnyConnect (SSL VPN on IoS) - Connection stuck on Android

I have an Any Connect WebVpn (ssl vpn?) set up on an IOS 15.2(4)M4. My current WebVPN is set up for Cisco Phones to use SSL VPN to connect to a Cisco Call Manager (CUCM 9.x). I also tried connecting with an Any Connect client from a PC and it seems to work fine.

Hi,
I'm having the same issue please let me know if yo found the solution. Thanks in advance

Dynamic DNS for ipv4 AND ipv6?

tl;dr: do you know any dynamic dns service and updater daemon that supports both ipv4 and ipv6?
Hi,
ever since my provider supplied me with a proper dual stack account (real ipv4, real ipv6) for internet access I got some kind of little problem regarding the services I host at home. So this is mainly about email. I have a server sitting behind my router that has an open submission and IMAPS port. For ipv4 I've been using the NAT and dyndns features of my router (fritzbox) without any problem. For ipv6 there is no NAT (at least as far as my router is concerned). What I can do though is to open the firewall for incoming ports dynamically based on the interface identifier. So if someone wants to connect to an ipv6 address that would map to my server the router knows to not block the traffic. For this to work though I need update a dynamic DNS record with the public ipv6 address that my server gets to use (something out of the prefix my provider assignes me). This server is an arch linux box. I tried to use inadyn-mt with some systemd unit file I found through google but this does not seem to work right. When I'm in ipv4-only networks (on a mobile connection for example) I often can't resolve the right ip address of my server through dyndns. The thing is that my server doesn't know about a changed ipv4 address because this is handled by the router. It does only know about when his own ipv6 address changes/expires. Based on when this happens inadyn-mt might fire an update to dyndns and with that also pick up the new ipv4 address, but this is not guaranteed.
Any suggenstions, tool and/or service proposals? Is there a way dns-wise to add a CNAME alias just for A records and not for AAAA?

I currently use cloudflare as the DNS servers for my domain as it's free and allows to update certain records with their API. I only use it for IPv4, but since they support AAAA records, I assume it will work for IPv6 just as well. It should be quite simple for you to update the script to get the ip of a given interface instead of fetching it from the net.

Actiontec MI424WR-GEN3I with ChangeIP dynamic dns

I'm trying to configure my router (Actiontec MI424WR-GEN3I, v. 40.21.10.3) with ChangeIP.com dynamic DNS. It's listed in the provider drop-down in the Dynamic DNS section of the router GUI, so i figured i'd be all set. I setup an account with ChangeIP, and then got a hostname from them.
In the router i'm configured as follow..
Hostname: MyHost.changeip.com (<-- actually MyHost.onmypc.org; "onmypc.org" being one of the domains ChangeIP offers for free.)
Connection: Broadband Connection (Ethernet/Coax)
Provider: changeip.com
Username: My changeip username
Password: My changeip password
Dynamic DNS System: Dynamic DNS
Offline: (not checked)
SSL Mode: None
In the status area it just says "Error - Unknown changeip.com error". There's nothing in the changeip knowledgebase. Has anyone tried configuring changeip on their router? I know they have something called homeing beacon, but really i just want this to work as configured without having to install anything extra.
Thanks!

Hello, I had the exact same problem. It seem Verison FiOS router is not very flexible. You can't enter another Dynamic DNS (DDNS) and can only use one on the list. The only two free one I found was no-ip.com and changeip.com.
The no-ip.com came back with a host not found cause they've changed the name to noip.com (without the dash) so the dumb router is not able to find it.
The changeip.com is no help either as you've found out. I keep getting Error but it does not say why. Fortunetely I did found a solution. You can download changeip.com's DDNS Update Client (for Windows, Linux, or OSX). The called this software as Homeing Beacon.
http://www.changeip.com/accounts/downloads.php
In Windows it runs as a self startup service so you don't to remember to run it but you will need a Windows PC to be on for the update to occur. Basically instead of updating changeip.com's DDNS entry from the router, you have a Windows client that somehow figures out what the router's IP and act as a proxy agent and update your DNS entry on changeip.com. This is a workable workaround, I think. The drawback is you need a PC running every so often on your home network so updates occur. But, the price is FREE and you can't beat that.
