VPN

i have a router 1841. i have configured it for site to site connection with an ASA 5510, the configuration is working perfectly. Next i configured the router for VPN remote connection and it worked but it stopped the site to site connection.

my problem was that i configured both with the same NAME of crypto map but with different sequences and different encryption too.

I changed the name of the crypto map for the site to site and it worked again but the VPN remote connection is not working.

Is there a solution for my problem, having one internet connection and one router???

You need to use the same crypto map name but the key is the remote access VPN sequence number be higher than the site to site.  Good practice is to use 65535 for the remote access VPN sequence number.

Looks good.  Can you post access-list 170 and the vpn-split-tunnel access-list.

with this config, the site to site stops from working. Maybe from this access-list???

access-list 180 deny   ip 195.125.1.0 0.0.0.255 195.125.10.0 0.0.0.255
access-list 180 permit ip 195.125.1.0 0.0.0.255 195.125.50.0 0.0.0.255

hi JFrederick, i did what u told me but still didn't work. the problem was with the username and password. The site-to-site was not working coz of it. i created isakmp profile for site-to-site and vpn client so that the site-to-site wouldn't use the username and password and it worked very well. Thank you anyway.
