IPsec transport mode with IPv6?

I am trying to set up IPsec in a IPv6 environment. However, when I configure "crypto map" I wasn't able to "set peer" to a IPv6 peer address. Why is that?
I used Virtual Tunnel Interface instead of Crypto Map and it worked. But I need to IPsec in transport mode instead of tunnel mode.

I think here is no support for mixed mode which is ipv6 traffic through ipv4 tunnel and vice versa in VTI . Better solution is Gre tunnel.

IPSec Transport Mode

Hi,
I am trying to setup an IPSec transport mode policy from my test server in the office to a VM in Azure in order to replicate data to a RODC.
Both servers sit behind a NAT firewall and have private IP addresses.
I have created a security policy at each end which specifies both the private address of the server and the public address of the cloud service (Azure) and firewall (On Prem)
I have opened firewall ports on both sides to allow both 500/udp and 4500/udp
Using the Network Monitor tool, I can see some IKE transmissions but I can't ping/rdp either way.
Any ideas?
Thanks
Dave

IPSEC transport mode and GET VPN

All,
I am about to implement GET VPN while read the following from Cisco's website:
IPsec transport mode suffers from fragmentation and reassembly limitations and must not be used in
deployments where encrypted or clear packets might require fragmentation.
I just do not understand why transport mode will suffer fragmentation and reassembly while it had less overhead than tunnel mode.

One thing to understand about Tran sport mode vs Tunnel mode (ipsec) is thst Transport is used between acyual source and destination of the ip protocol
Tunnel mode actually not only authenticates but also encrypts at the higher layers of the pckt
Pix
VPN
IP layers
Tunnel actual source and destination is encrypted at the upper layers and therefor when the packet gets to the IP Layer, it really doesnt know about or care about the iCV signature already withinh the upper PIX layer.
Also from a security standpoint because of the fact that tunnel mode encrpyts and authenticated the ip infoemation whereas transport only authenticates packets

IPSec (transport mode) load balancing via CSM

Suppouse that there is two servers providing service for remote aplications. Those aplications using IPSEC in transport mode. I would like to put at front CSM to load-balance beetwen both of them (persist via SRC IP is ok for me).
Have you any expirience with transort mode? IMHO it is not possible becouse of ip header changes? (I have no exact informatin that resign from AH transforms are possible)
What when changing to tunnel mode. Have you ever seen that configuraion working?

I think you can for the transport mode. I have not had any luck with the Tunnel mode.

IPSEC ESP SECURITY PROTOCOL IN TUNNEL & TRANSPORT MODE

My query is that who much IP Pachet is
added/expanded in following two case.
1. ESP IN TRANSPORT MODE.
2. ESP IN TUNNEL MODE

Transport mode: 37 bytes 3DES or 63 bytes AES
Tunnel mode 57 bytes 3 DES or 83 bytes AES
M.
Hope that helps, rate if it does

Can't get Transport Mode to Work

Just messing around in a lab with a few routers. Trying to bring up transport mode first on an IPSEC tunnel. All seems correct, but it constantly comes up in Tunnel Mode. I can't see why?
Can anyone see anything obvious?
Enclosed are configs and a WireShark capture of the output - as you can see it's Tunnel Mode - and not Transport.
The output of "show crypto ipsec sa" demonstrates the fact that its Tunnel mode.

Thanks for the reply Rick.
The access list is a catch-all :-
access-list 100 permit ip any any
It's a strange one to grasp really.
"traffic to be protected has the same IP addresses as the IPSec peers "
My routers are peers - 192.168.1.1 & 192.168.1.2
If i ping from .1 to .2, or .2 to .1, in my mind this represented "the same IP addresses as the IPSEC peers". Other than the ping, i don't know how i can simulate peer traffic that would come up in transport mode. Do you?
Once the IPSEC link is built, and it's a tunnel link, i don't think it will ever divert away from this and create a separate transport mode link, so all traffic will ride across it.
It's not a big deal i suppose. Router to router connections don't seem to support transport mode.
I know how the packets would look like, which is the most important thing really. The headers are just in different positions.
Thanks again for taking the time to answer Rick.

IPSec tunnel mode vs self-encapsulation ESP

Hello
I need to develop some server application which should communicate with thousands of independent external clients through IPSec in tunnel mode.
Configuration of IPSec must be done dynamically from application.
There is a requirement to have the same source/destination IP address in the inner and in outer IP headers, tunnel must start and ends within the server and within each client.
Is there any way to activate IPSec in tunnel mode without tunnel configuration?
In Solaris documents I see that there is possibility to activate self-encapsulation ESP mode.
Is this mode is the same as IPSec in tunnel mode?
If answer is yes, then is it possible to activate this mode system-wide, but not per-socket?
Thanks.

Additionally to some proprietary data connections we need to provide FTP server for clients over these IPSec connections.
Standard Solaris ftp server will be used.
Will IPSec with ESP in transport mode over NAT give us such possibility?
As far as I know FTP encapsulates IP addresses during it's work, so we think that only ESP tunnelling can provide normal working of FTP over NAT.
Is it possible to configure such kind of tunnel in Solaris as described in my first mail?
"There is a requirement to have the same source/destination IP address in the inner and in outer IP headers, tunnel must start and ends within the server and within each client."

Importing content: transport modes 'all', 'data'

I try to import *.epa file and get error for evere entity in package:
PcdGlTransportManager.importObject(): cannot import an object in transport mode all that has been exported with transport mode data.
It seems the thing is in transport mode. How to change it?

Hi Denis,
I am facing same problem whiile importing BP for ESS & MSS (ERP 2005NW04s) into EP NW04(6.0 sp14).
Either i can modify all .properties files as suggested by you or we can upgrade EP to 04s (7.0).
Did you face any problem after modifying all 'data' to 'all'; is it working fine?

Distributed Database with IPV6

Distributed database was not that familiar few years before...will IPv6 enhance the distributed database systems ? DDBMS has wide range of best features & notable drawbacks to..however today's business need of distributed database. contribution of DDBMS in Cloud computing.

Do not confuse the communication transport layer with the ability of the database to support distributed integration. Even NetBEUI can be used (assuming that protocol routing is not needed). Distributed database is not about protocol dependency.

PTP Transport mode

Hi All,
I'm trying to configure the PTP on the ASR9001 and I'd like to use the transport mode ETHERNET instead of IPv4.
From the RP/0/RSP0/CPU0:ASR9001-2#show ptp interfaces it look likes that the Ethernet capability is not supported:
TenGigE0/0/1/1 is in Master state
PTP port number: 1
IPv4 transport: IPv4 address 10.85.52.5
Linestate: Up
Mechanism: Two-step delay-request-response
Sync rate: every second
Announce rate: every 2 seconds, timeout 3 intervals
Min Delay-Request rate: every second
CoS: General 6, Event 6, DSCP: General 46, Event 46
Platform capabilities:
    Supported:     One-step, Two-step, IPv4, Unicast, Master, Slave
    Not-supported: Ethernet, Multicast, IPv6, Source IP
    Max-Sync-rate: 128 per second

0 Unicast peers
Can you please support me?
thanks in advance.

ASR9000 BVI with IPv6 on Typhoon

Hello Guys,
http://www.cisco.com/en/US/docs/routers/asr9000/software/asr9k_r4.3/interfaces/configuration/guide/hc43irb.html#wp1030916
Hope that this is just (another...) bug on the documentation, and that BVI is supported with IPv6 on the Typhoon LCs. Anyone can confirm it?
David

Thanks the issue i have it was discused on other two cases under the support community,
Thnaks to Mattew Ayre y
MAttew "The reason it doesn't work is because label switching on a VRF aware BVI is only supported in the per-vrf label allocation mode. There's a mention of this in the configuration guide shown here;
"VRFs for IPv4 (Per-VPN label VRFs only—not per prefix)"
http://www.cisco.com/en/US/docs/routers/asr9000/software/asr9k_r4.1/interfaces/configuration/guide/hc41irb.html#wp1030591
The change you should be able to observe is that if you create a second route, for example 192.168.200.66/32. It will be allocated the same label as the .65/32 prefix. When using per-prefix label allocation mode the label for each prefix would be unique.
You should be able to verify this with "show mpls forwarding vrf Ga" after adding an additonal route.
HTH,
Matt Ayre"

Hi Pichet,
Thx for opening the ticket and here is the summary of our troubleshooting session for the rest of the world
BVI does not support native MPLS forwarding and hence we need to use per-vrf allocation mode:
http://www.cisco.com/en/US/docs/routers/asr9000/software/asr9k_r4.1/interfaces/configuration/guide/hc41irb.html#wp1030591
With this configuration we'd use an aggregate label and would do VRF IP lookup instead when a packet arrives from the core.

E72 problem to activate silent mode with 031.023

now it is very difficult to activate silent mode with the ctrl key !

I think this is not a bug, but a fix. In the previous FW it was TOO easy to switch to Silent mode and that would happen quite often by mistake (at least to me).
So I think that Nokia corrected this problem, but did not communicate properly with their customers....

How do I exit TDM?
To leave TDM, press Command-F2 on the keyboard of the iMac that is in TDM. You can also exit TDM if you shutdown or sleep either computer or detach the cable.
Can I use a third-party keyboard or older Apple keyboard to enable TDM?
Some older Apple keyboards and keyboards not made by Apple may not allow Command-F2 to toggle display modes. You should use an aluminum wired or wireless Apple keyboard to toggle TDM on and

Firefox plug in container has stopped working, even in safe mode with plug ins disabled

My firefox keeps crashing every 5 - 10 minutes. Sometimes I get a windows error message saying "firefox plugin container stopped working", but most times I don't. These are the actions I've taken so far, with no effect:
1. Updated all my plug-ins
2. Run firefox in safe mode with plug-ins disabled
3. Uninstalled and reinstalled firefox
4. Run an AVG scan which turned up nothing
Can anyone offer advice on how to fix this (very annoying) problem?
I've had to write this in IE because firefox wouldn't stay open long enough for me to copy and paste it into the text box.
