I am trying to make a VPN connection between two Cisco VPN Firewalls that are sitting in behind an Astaro and a ZyXEL that are connected via a site to site IPSec on the Astaro.
LAN 1: 192.168.31.0/24
Cisco 1 Internal: 192.168.31.1
Cisco 1 External: 192.168.21.1
ZyXEL Internal: 192.168.21.254
ZyXEL External: 88.x.x.x
Astaro External: 213.x.x.x
Astaro Internal: 192.168.10.13
Cisco 2 External: 192.168.10.41
Cisco 2 Internal: 192.168.0.1
LAN 2: 192.168.0.0/24
192.168.31.0/24 can connect to 192.168.10.0/24; but the VPN traffic from Cisco 1 isn't reaching Cisco 2. Obviously the traffic is being blocked at the Astaro but I can't find anything in logs to suggest where the problem might be. Any suggestions would be welcome.
