Hi

Can you revert what kinda VPN you have deployed over there between ur locations ?

also are you trying out this command ip tcp adjust-mss to tweak the mss ?

Also can you paste the show version o/p of your router over here..

hi

As per the data sheets available this feature was introduced in 12.2(4)T ,command migration from ip adjust-mss to ip tcp adjust-mss happened in 12.2(8)T.

upgrade the ios code to 12.2 GD version to have the command configured under ur interface...

Hi,

you need a CCO account to download IOS software from

http://www.cisco.com/public/sw-center/products.shtml

Providing you an IOS without you being entitled to get it would be a copyright violation.

Hope this helps
