Fun with VPNs - Port Forwarding

I have a UC500 on one side and a combination of a SR520 and an unnamed firewall on the other side.

I am created a VPN tunnel between the two.  I can make the UC500 to SR520 work no problem.  Once I insert the unnamed firewall, it becomes dicey.

Basically I have 1 public IP address.  I need to forward the vpn traffic from the firewall to the SR520.


What ports do I need to forward?

Thanks for any help.

Check out this app note for ideas on which ports are involved in IPsec.
