I have a Cisco ASA 5510 which is connected to the internet - this is my only internet connection - I have a watchguard firewall which I would like to make visible outside the ASA and have the VPN traffic flow inside, along with other types of NATs. I'm not sure how to make the outside address of the Watchguard visible though the ASA and allow all the traffic to flow freely though the Watchguard. Can someone point me in the right direction. I know I need the following ports open for this to happen
UDP port 500 (IKE)
UDP port 4500 (NAT Traversal)
IP protocol 50 (ESP)
I have access to both ASDM and putty.
