Watchguard firewall

Hello, I have a client that has a Pix 515 firewall and I have a Watchguard Firebox 1000. He gave me the Cisco vpn 3.5 software to install. My question is, what ports do I need to open on my firebox to allow outbound and inbound communications to his firewall? Any help is greatly appreciated.

Re: Watchguard firewall

Hi Jeff,

As can be seen in the following allowing PPTP through the PIX:

http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a0080094a5a.shtml

You can just replace the ports for PPTP to those for IPSec and get going on this:

Ports to allow for IPSec:

UDP port 500, IP protocol 50 (ESP), IP Protocol 51 (AH).

Additionally if they are doing any IPSec/NAT ports then you need to open those aswell, but confirm those with them as it depends on what the terminating device is for it.

Regards,

Aamir
