Hi,
I have an ASA 5510 in our central office that connects our other offices around the country (The smaller offices has ASA 5505:s). All but one office is on static public ips, which has a dynamic public ip.
I do site-to-site tunnels to all the offices but i have a problem with the dynamic one.
The dynamic tunnel has it's own external ip in the 5510 in the CO, cause i've understood that's the only way to do dynamic tunnels in ASA. This causes a problem since the default route is to another interface (the main external adress of the asa). I tried to add a static route for the current dynamic ip to the gateway of the second interface and that brought the tunnel up, but i don't like having to add a new static route every time the ip changes :-)
Does anyone have any good ideas how to solve this?
I have access to the router (cisco) the CO-FW is connected to and i have several public IPs left to use if this will help.
Thanks in advance, Alexander
