PIX 6.3 won't pass traffic when VPN'd in from another PIX firewall

Hello all

I upgraded several customers to ver 6.3 from 6.x. They all had working vpn set up on the firewalls. The big thing about 6.3 was supposed to be able to let you now vpn from behind a pix firewall to another pix. The only catch was you had to have 6.3 on both firewalls. I can connect to the firewall but I don't pass traffic. If I go to an outside connection I can pass traffic. Anyone else in the same boat. I have one customer that has a TAC case 6 feet long and still no resoluation.

If you are talking about PPTP from behind a PIX, then yes, 6.3.1 fixes this problem with the fixup prot pptp 1723 command

If you are talking about IPSEC/IKE then this will not work if you are doing NAT, no matter which version IOS you are running.

If you provide a little more detail on what vpn technologies you are trying to use, I might be able to help more.
