Problem ASA5505 IPSEC VPN was created by Quen
Hey Guys,
I'm trying to set up a VPN Site-to-Site tunnel using a cisco ASA5505 and a Linksys WRV4400N. The tunnel is UP. But it isn't working. I think this is because of our tight access list. Can u please help.
Cisco ASA5505
External IP: 195.241.X.X
Internal IP: 192.168.135.0 255.255.255.0
Linksys WRV4400N
External IP: 195.93.X.X
Internal IP: 10.10.1.0 255.255.255.0
I will post my config below. Thanx in advance!

If you suspect an acl issue, why don't you allow any any in your access list and see if that works before you start to tighten it.
However, from the config, I don't believe you are even making it through the isakmp stage.
