Include multiple sub-interfaces in Cisco ASA for VPN tunnel
I am trying to create a VPN tunnel between two Cisco ASAs where one ASA has multiple sub-interfaces.
Say, In Cisco ASA 5550(in datacentre), I created multiple subinterfaces with VLAN ID as below:
Inside, int0/1 : 10.1.1.0/24
DMZ, int0/1.100: 10.1.100.0/24 (VLAN 100)
Production, int 0/1.101 : 10.1.101.0/24 (VLAN 101)
Management, int 0/1.102: 10.1.102.0/24 (VLAN 102)
And another Cisco ASA 5505 is only configured with 1 x inside interface Inside, int 0/1: 192.168.1.0/24
So far, I have only been able to provide outside access to one of the sub-interfaces as NAT rule on inside interface didn't work for VLANs. Hence had to issue Global NAT rule to be applied on Production subinterface so that production VLAN can have outside access. I have managed to establish VPN tunnel between two ASAs on Production sub-interface only, Source interface = Production subinterface
Additional settings:
Have ACL to allow all sub interfaces to access outsite ( lower security level)
NAT rules is configured on Production subinterface with Source NAT Type as Dynamic PAT; when this was configured with source interface as inside, PCs behind various VLAN coun't access internet.
I want to establish a site-to-site VPN tunnel with multiple sub-interfaces of Cisco ASA 5550 to Cisco ASA 5505. Would you please suggest what I am missing in my configuration? I need to be able to access multiple VLANs of datacentre from remote site.

High receive discards on Sub-Interfaces in Cisco ASA.
Hello Everyone,
Over the past few weeks Solarwinds is reporting high receive discards on two of our subinterfaces created on Cisco ASA. No errors are observed on other subinterfaces. I checked the trunk port interface on the switch for any errors but found none. These errors are visible only under subinterface. What could be the issue?
RegardsI have the same problem too.
I have Cisco ASA 5515 with the next version:
Cisco Adaptive Security Appliance Software Version 9.1(4)
My interface configuration is the next:
PortChannel5 made with Interface GigabitEthernet 0/2 + Interface GigabitEthernet 0/3
Subinterfaces in PortChannel5
Nagios Graphs shows:
- many input discards in virtual subinterfaces
- many output discards in interface Gi0/2 and Gi0/3
- PortChannel5 output discards is the sum of discards in interface Gi0/2 and Gi0/3
if I run the snmpwalk command against the ASA the following results were obtained:

2 ASA for VPN tunnel hub and Dual tunnel to both from cisco1800
I am struggling with configuring Cisco1841 to have dual or back up tunnel to two seperate ASA's on our corporate network. There is alot of great doco on DMVPN with routers as hub but is DMVPN the best way to configure this router and the others to fallow. I have no issues creating single normal tunnel to either ASA when I try to get tunnel to each I have issues.
Last attemtp of DMVPN config on 1841

I think I have to do the access-list differently. The only way I know how to add routing is if I do tunnel interfaces and I have only done that with router to router tunnels. Is there a way to do that on a Router to ASA configuration?

Configuring Cisco ASA for site to site VPN ( Issue with setting up local network)
OK, so our primary firewall is a checkpoint gateway. Behind that we have a cisco ASA for vpn users. I have a project at the moment where we need to connect to another company using site to site VPN through the cisco ASA, as the checkpoint gateway is unable to establish a permanent tunnel with the other companies Cisco ASA.
What would be the best practise for setting up the local network on my side? Create the network on the ASA and then use a L2 vlan to connect to the Core switch?
Setup a L3 interface on the core switch and point it towards the checkpoint gateway which would then point to the ASA?
When you have to select your local network through the site to site wizard do you have to put the inside network address of the ASA?
Our network is setup like this: Access layer switch > Core 6500 Switch > Checkpoint-Firewall > Internet
The ASA is connected to a checkpoint sub interface
Any help would be beneficial as im new to cisco ASAs
Thanks
MarkMark
If we understood more about your environment we might be able to give you better answers. My initial reaction was similar to the suggestion from Michael to use a L2 vlan. But as I think a bit more my attention is drawn to something that you mention in the original post. The ASA is there for VPN users. If the VPN users need to access your internal network then you probably already have something configured on the ASA that allows access to the internal network. Perhaps that same thing might provide access for your site to site VPN?

Can I rate-limit on the sub-interface in cisco asr 1013?
Hi,
I am looking for the command of rate-limit on a sub-interface in cisco asr 1013.
Cisco IOS Software, IOS-XE Software (X86_64_LINUX_IOSD-ADVENTERPRISEK9-M), Version 15.2(2)S, RELEASE SOFTWARE (fc1)
IOS XE Version: 03.06.00.S
Please let me know if it is possible in cisco asr 1013. If yes then what are the commands.
ZobairThe ASR no longer supports the rate-limit command, but it does support the same functionality in a QoS policy.
Please find a sample configuration -
ASR1004(config)#policy-map test
ASR1004(config-pmap)#class class-default
ASR1004(config-pmap-c)#shape average 10000
Applying for both ingress and egress : -

Access Site to Site Networks behind Cisco ASA thru VPN Client
I have configured remote access thru asa for vpn clients to our main network. I can ping the required networks from vpn client. Internally I can ping remote network thru our sonicwall site to site vpn. I however cannot ping the remote network from the vpn client. I've added the network in the configuration on the ASA that I am trying to connect to. Any ideas what I can do so I can connect to Site B thru my vpn client connecting to Site A?
Thanks,
MattHello, matt0000111111.
Did you add a VPN clients network to the sit-to-site VPN settings and to the NAT list (if nat exist at the interfaces at site-to-site vpn)? -
Cisco ASA 5505 VPN help for local lan access.
Hi all,
I am very new to Cisco systems. Recently I was tasked to enable local lan access for one of my server. The problem is this. I have this server with 2 interfaces. One interface to my FTP server(192.168.2.3) and the other to the Cisco ASA(192.168.1.1). Whenever I connect the server to Cisco Anyconnect VPN, I am unable to access the FTP server anymore.
I googled and found out that the problem is because the metric level is 1 for Ciscoanyconnect network interface which causes all traffic to go through the Cisco VPN Interface. Another problem is I can't change the metric of the Cisco VPN Interface as whenever I reconnect to the VPN, the metric resets back to 1 again. I tried to follow some guides to configure split tunnel but my traffic is still going through the VPN connection.
Anyone can tell me what I am missing here? Sorry I am very new to Cisco systems. Spent about 5 days troubleshooting and I feel I am getting it soon. Anyone can guide me what else I am supposed to do?
What I did> Configuration>> Remote access VPN>> Network Client Access>> Group Policies>> Advanced>> Split Tunneling>> Uncheck Inherit and select "Exclude Network List below.>> Uncheck Network List and select Manage, Add 192.168.2.0/24 to permit.
Really appreciate if anyone can tell me what else I can do to ensure my server has access the my FTP Server after connecting to the VPN.
Thanks all!
Wen QiHi,
Try adding the following configuration
policy-map global_policy
class inspection_default
inspect pptp
And then try again.
I'm not 100% would you need to perhaps allow GRE through the firewall even after that. (Protocol 47)

Port Forwarding for Cisco ASA 5505 VPN
This is the Network
Linksys E2500 ---> Cisco ASA 5505 ---> Server
I beleive I need to forward some ports to the asa to use the IPsec VPN I just setup. I had the SSL VPN working but only needed to forward 443 for that....I assume that IPsec tunnel is a specific port.
Thank YouFor IPSec VPN, you need to port forward UDP/500 and UDP/4500, and remember to enable NAT-T on the ASA.
Command to enable NAT-T on ASA:

I believe when a VPN tunnel is setup there should be one Child sa per subnet. The internal network of 10.65.1.0/24 should be setup with a child sa to the networks that were specified above depending on if there is traffic destined for them. What I am seeing is multiple child sa setup for the same subnet like the example below:
GARPR-COM1-WF01# sh crypto ikev2 sa | i 172.19
remote selector 172.19.0.0/0 - 172.19.255.255/65535
remote selector 172.19.0.0/0 - 172.19.255.255/65535
remote selector 172.19.0.0/0 - 172.19.255.255/65535
remote selector 172.19.0.0/0 - 172.19.255.255/65535
remote selector 172.19.0.0/0 - 172.19.255.255/65535
remote selector 172.19.0.0/0 - 172.19.255.255/65535
remote selector 172.19.0.0/0 - 172.19.255.255/65535
remote selector 172.19.0.0/0 - 172.19.255.255/65535
remote selector 172.19.0.0/0 - 172.19.255.255/65535
remote selector 172.19.0.0/0 - 172.19.255.255/65535
where for destination network 10.92.0.0/16 there is only one child sa:
GARPR-COM1-WF01# sh crypto ikev2 sa | i 10.92
remote selector 10.92.0.0/0 - 10.92.255.255/6553
Should this be the case or does anyone have any idea why there is multiple child sa setup for the same subnet?
Thanks
JonathanHi there,
I had same issue with PIX 506E and it was not even a circuit issue and I got ride of it and problem got fixed with PIX515E
I don't know, the device is too old to stay alive.
thanks -

Any idea why it's not working?You've got a lot going on there but I'd focus on the line "no vpn-addr-assign local". Per the command reference that tells the ASA NOT to use the local pool.
By the way, DHCP on the outside interface looks very counter-intutive, as does enabling VPN on all interfaces over every protocol. -
Cisco ASA Anconnect VPN Deployment
Hi,
I have an enquiry regarding the deployment for ASA that need to support more than 10000 clients. I understand that multiple ASA would be required for it however I was wondering what may be the typical design for it? Should the multiple ASA be setup as vpn cluster/load balancing/etc...?
It would be appreciated if there are any design document for it. The present setup is a pair of ASA active/standby was wondering on how to combine the total connection if I require 15000 vpn connections; example 2 pairs of active/standby with vpn clustering/load balancing/etc...?
Thanks.You are right, the vpn-loadbalancing is the technologie you should deploy for that. With that you can combine multiple devices to a load-sharing cluster. These devices can be different, for example two 5555 with two 5545 which would give you atotal of 15000 VPN-connections.
Of course you should plan for device-failure. So you could deploy 4*5555 and also if one ASA is lost you still have 15000 connections (well, at least based on the data-sheet; I wouldn't push the amount of connections to the limit).
For redundancy you could also deploy these devices also as FO-systems. 3*2*5555 would also give you redundancy.
This is all under the assumption that the users connect to the same office where the ASAs have a L2-connection to each other which is needed for VPN-loadbalancing. If the users connect through different locations, then these ASAs can't use VPN-loadbalancing unless you have a L2 connection between the loacations.
If you have multiple locations you should also think about the shared-license server which could save a lot of money if your users don't always use the same gateway.
And the last point: configure as much as possible for your AAA with a central RADIUS-server to reduce the probability of misconfiguration on multiple ASAs.

CISCO ASA 5505 Split Tunnel DNS with Site to Site VPN
I have a working configuration for Site to Site VPN between our head office and a private AWS VPC instance.
The tunnel is active and I can ping the IP address of the remote network and connect to the remote machines using the IP address, but we need to use the FQDN and not the IP. We have a DNS server set up in AWS for any DNS queries for the remote domain name.
My question is whether or not the ASA 5505 supports a DNS split tunnel for Site to Site VPN and how it can be configured.
I can not find where I can interogate the DNS query to be redirected to the VPN tunnel when our domain name is used in a DNS query. Thus, any pings I try with the FQDN of our servers in AWS are failing as they are going to the default DNS, which is the internet.
Can any one point me in the right direction on how to configure this DNS rewrite so that we can access our AWS private cloud using FQDN from our AWS domain rather than an IP address?Jose, your fix to problem 1 allows all access from the outside, assuming you applied the extended list to the outside interface. Try to be more restrictive than an '...ip any any' rule for outside_in connections. For instance, this is what I have for incoming VOIP (access list and nat rules):
access list rule:
access-list outside_access_in extended permit udp any object server range 9000 9049 log errors
nat rule:
nat (inside,outside) source static server interface service voip-range voip-range
- 'server' is a network object *
- 'voip-range' is a service group range
I'd assume you can do something similar here in combination with my earlier comment:
access-list incoming extended permit tcp any any eq 5900
Can you explain your forwarding methodology a little more? I'm by no means an expert on forwarding, but the way I read what you're trying to do is that you have an inbound VNC request coming in on 5900 and you want the firewall to figure out which host the request should go to. Or is it vice-versa, the inbound VNC request can be on port 6001-6004 ? -
Cisco ASA 5505 VPN connection issue ("Unable to add route")
I'm trying to get IPSec VPN working onto a new Cisco ASA5505. Pretty standard configuration.
Setup:
* Cisco VPN client on Windows 7 (v5.0.07.0290 x64 on Laptop1 and v5.0.07.0440 x64 on Laptop2)
* PPPoE/NAT and internal DHCP on the ASA were configured with the Startup Wizard in ASDM
NATting is working fine - internal PCs get an IP address in the 192.168.2.0/24 range and can all access the Internet.
I wanted to be able to connect from anywhere to the ASA in order to reach one of the internal servers. Should be pretty basic.
First I tried with the built-in ASDM IPSec Wizard, instructions found here.
VPN clients can connect to the ASA, are connected (until they're manually disconnected), but cannot reach the internal network nor the Internet. Note VPN client can connect fine to a different VPN site (not administered by myself).
Client logs show following error messages:

I've already tried the suggestions from this link, although the problem is different there (as the user can still access the internet, even without split tunneling, which I cannot).
A show run shows the following output (note in the below I have tried a different VPN network: 192.168.3.0/24 instead of 172.16.1.0/24 seen in the Client log)

Unfortunately I'm getting the same "AddRoute failed to add a route with metric of 0: code 160" error message.
I'm very confused as this should be a pretty standard setup. I tried to follow the instructions on the Cisco site to the letter...
The only "differences" in my setup are an internal network of 192.168.2.0 (with ASA IP address 192.168.2.254) and PPPoE with DHCP instead of no PPPoE at all.
Does anyone know what's going on?Yes, I have tried from a different laptop - same results. Using that laptop I can connect to a different IPSec site without issues.
Please find my renewed config below:

Cisco ASA 5505 VPN Routing/Networking Question
I have a very basic question about Cisco ASA 5505 IPsec Site to Site VPNs. I want to install a Cisco ASA 5505 at a Data Center, in a LAN subnet that utilizes publicly routable IP addresses. I would like to install a second Cisco ASA 5505 in a remote branch office as its peer.
Regardless of whether I use publicly routable IPs at the branch office in the "inside" network or non-routable IPs, how would the devices and servers at the Data Center know to route IP packets destined for the branch office back through the Cisco ASA instead of through the default gateway at the Data Center? I can see accomplishing this if every single device at the Data Center is configured with routing table entries, but that isn't feasible. It also isn't feasible to use the Cisco ASA 5505 as the default gateway for all of the devices as the Data Center, allowing it to decide where the traffic should go.
What am I missing? Is the solution to try to map branch office IPs to IP addresses within the Data Center's LAN subnet so that all of the traffic is on the same subnet?You can do it in several different ways.
One way is to tell the server that if it has traffic to network x then it needs to go to the ASA all other traffic is to head for the default gateway.
In windows this is done via the route command
do not forget to make it "persistent" otherwise the route will disapear when your reboot the server.
in unix/linux
It is also the route command
Or you can tell your "default gateway" to route that network to the ASA
Good luck

I've got a new 5505, and I've run through two wizards: one to start up, one to add client VPN. As a result, I can now connect from a client, the client gets the right info (ip adress, dns, gateway), but it cannot connect to any of the servers on the 'inside' network. The config is here:
http://www.dubbele.com/asaconfig.txt.
I've tried a lot of different things, but I cannot seem to get what's going wrong. Any clues would be very welcome!John,
I strongly suggest to always use different ip-scheme for each of vpn RA tunnels and that they not be the same any of the asa inside interfaces.
interface Vlan1
ip address 192.168.6.25 255.255.255.0
ip local pool vpnhaarlem 192.168.6.150-192.168.6.175 mask 255.255.255.0
for vpnhaarlem do the following.
use a unique private IP scheme for it as you have done with rotterdam , as an example lets use 10.20.20.0/24
remove
no ip local pool vpnhaarlem 192.168.6.150-192.168.6.175 mask 255.255.255.0
add
ip local pool vpnhaarlem 10.20.20.1-10.20.20.254 mask 255.255.255.0
This first line acl is ok but persoannly I suggest to be more granular allowing specific RA tunnel group networks and not just permit ip any, again example for 10.20.20.0/24 network .
stick with one no NAT acl for RA tunnels like inside_nat0_outbound remove the 1 and 2 otherwise you will have to create more
nat (inside) access-list statements for RA networks.
remove
no access-list inside_nat0_outbound_1 extended permit ip any 192.168.6.0 255.255.255.0
no access-list inside_nat0_outbound extended permit ip 192.168.6.0 255.255.255.0 192.168.6.0 255.255.255.0
add
access-list inside_nat0_outbound extended permit ip 192.168.6.0 255.255.255.0 10.20.20.0 255.255.255.0
for the rotterdam tunnel group it is fine with unique IP scheme , I would apply my suggestion above
no access-list inside_nat0_outbound_2 extended permit ip 192.168.6.0 255.255.255.0 192.168.6.128 255.255.255.192
access-list inside_nat0_outbound extended permit ip 192.168.6.0 255.255.255.0 192.168.5.0 255.255.255.0
re-adjust the no-nat acl statement bellow
no nat (inside) 0 access-list inside_nat0_outbound_2
nat (inside) 0 access-list inside_nat0_outbound
Let us know how it works out
