I don't think you can do this. Site-to-site vpn's don't support udp encapsulation.So it's not tcp port 50 you need to open, but ip protocol 50. If the nat device supports natting of this protocol then maybe, so you could give it a try and check the logs of the pix too.

Hi all,

Again. Sorry about the first mail. It wasn't suppost to be sent unfinished so here I go again.

I have a small problem I need some new eyes on.

My setup:

Users [192.168.60.x] ---- FW/NAT ---- [172.16.x.y] Partner FW/NAT ---- ISP/Internet ---- HQ FW/VPN GW
                            |                           |                                      |
                         Nokia IP71                  Cisco PIX                          Nokia IP440 (MGMT)


My goal is to do site-to-site VPN between the two Nokia box's.

I have done a "fw putkey" on both enforcement points. The management station can se the IP71 and gives it the status "untrusted" in the System status windows.
Both run FW-1 4.1.

The setup has work in our test lab but there we didn't have a firewall/NAT device in between.

The PIX is doing STATIC NAT to my IP71. In the PIX port TCP 50 TCP 264 UDP/TCP 500 UDP 2746 in opened both ways. What I'm I missing?

Please help :o)


Best Regards,

Ole Jakobsen
