Hi, I can't get my site-to-site vpn to work. When I try to generate traffic from one internal host another. The trafic never arrives.
Traffic flow:
192.168.100.12 -> 192.168.100.1 -> 213.136.41.180 -> internet -> 79.136.112.50 -> 192.168.1.5
If the ipadresses on the other side of my tunnel are private 192.168.x.x, I need to add a route to outside ip address of that firewall right?
For example: route outside 192.168.100.0 255.255.255.0 213.136.41.180 1
One of my 5505:
access-list l2l_list extended permit ip 192.168.1.0 255.255.255.0 192.168.100.0 255.255.255.0

"If the ipadresses on the other side of my tunnel are private 192.168.x.x, I need to add a route to outside ip address of that firewall right?"
-NO
Add nat exemption to the ASA's.
First ASA-
access-list inside_nat0_outbound extended permit ip 192.168.1.0 255.255.255.0 192.168.100.0 255.255.255.0
nat (inside) 0 access-list inside_nat0_outbound
Second ASA-
access-list inside_nat0_outbound extended permit ip 192.168.100.0 255.255.255.0 192.168.1.0 255.255.255.0
nat (inside) 0 access-list inside_nat0_outbound
