VPN client able to connect but unable to ping router

michaelchandra · ‎02-27-2013

Hi, I'm new to cisco and I'm trying to make my own vpn. I've created the VPN using SDM because I'm not familiar with the Cisco IOS so I thought it'll be easier. When I'm trying to connect to my VPN, i was able to connect but I can't ping the router. I've done googling all day but I can't find the answer.

Below is my configuration :

Thank you

Shirshendu Nandi · ‎02-27-2013

config looksmore or less Ok to me .

1>

Remove the command reverse route from below

crypto dynamic-map SDM_DYNMAP_1 1

set transform-set ESP-3DES-SHA

reverse-route

2> if the above dont Solve then

Try remove both ACL from the interfaces 101 and 100 ..Reooot the router Once if possible and try again

Remove acl 100 and 101 from the interface and thereby reboot the router .

michaelchandra · ‎02-27-2013

Thank you for the fast response. I'll try that.

michaelchandra · ‎02-27-2013

I've tried that, but still no luck. Strange thing is that my vpn client log shows different error when i try to connect from another computer but using the same internet connection. Is that possible that the cause was my computer ip configuration ?
