Borderware Steelegate & VPN 3000 interoperate?

[art.henry]

I am attempting to setup a VPN solution (newbie) using a VPN 3000 concentrator behind a borderware steelgate firewall. Do these two product interoperate? I can bring up a session without the firewall but not when I place the firewall in front of the concentrator, I do know the firewall is passing the traffic through. Thanks in advance.

several things you may need to verify:

i. the concentrator has a public ip nat on the firewall, not pat but nat.

ii. firewall permit all the required traffic, including

udp 500, udp 4500 and depends on whether ipsec over tcp has been enabled, you will also need to permit that.
