L2L Dynamic VPN between 5510 and 5505

pert

Could you guys help me out with whats broken in here? I don't have much education on the VPN side. Config looks right to me, but it doesnt work and also breaks existing VPN connections.

192.168.0.0 /24 private
ASA 5505 - Remote Office Firewall, dynamic private IP on Outside Interface

Kind of a late reply, but I've labbed this up on 8.4 and it seems to run perfectly with your setup. There are a few differences in terms of NAT exempt but the tunnels came up without any issues. One issue I've encountered on 5520/GNS3 was when using the "ip address dhcp setroute", it obtained a DHCP address but did not set a default route.

Does your router behind your HQ ASA have routes for the remote site? Are you enable to run show commands to see if it is failing at phase1 / 2 or any debugs to see whats happening?
