Hi Everyone ,
I am facing a very big problem with site to site vpn on cisco 2900 ios.
i configured the vpn and when i ping from router itself to destination ip with source as lan interface , VPN works, no problem.
but when i connect any computer directly to router's lan interface to initiate traffic , it doesnot work at all. and on computer's lan i see yeloow sign.
mtu is 1500, speed is auto (i tried chaging also) , duplex is auto ( i tried changing also) , thoguh firewall on pc should not affect but still i disabled it.
since their is no problem with vpn config as vpn comes up when i initiate ping from router itself but i dont know why it is not working from lan.
do we need any inspect icmp on this router also ? or any policy modification to pass traffic across the interfac on router is required ?
i was useinf c2900k9-15.0(M4).bin and i upgraded it to 15.3 which is lated to get reed of any bug .
lastly , i connected two laptops directly to router's gi0/0, g0/1 interface to ping from one laptop to another but this also did not work.
any help is highly appriciated .
