[Sidewinder] Configuring GW2GW VPN between SideWinder 7 and Netscreen 25

[Sidewinder moderated discussion list]

You will need to take a close look at the audit log for VPNs.  You can do this using the command "showaudit -v > vpn.txt".  Then take a look at that text file with "less" or "more".  Then filter on the IP address of the Netscreen gateway and look for errors in the VPN negotiations.  You may need to increase logging verbosity by going to Policy --> Rule Elements --> Services --> isakmp.  Double click on that service and go to Properties.  You can change the audit level there.  Normal is generally good enough for me, unless I have a really troublesome VPN.  You might want to try Verbose. Debug will probably give you too much and make it had to track down what you need.  I would try it at the Normal level first.

Subject: [Sidewinder] Configuring GW2GW VPN between SideWinder 7 and Netscreen 25

Hi.

We have the following problem.
We had a SideWinder G2 that we had configured to build a
Gateway-to-Gateway VPN with a NetScreen 25.
Lately we upgraded to SideWinder 7 and now this VPN Configuration does not
work anymore.

We configured the VPN as it is described in SecureComputings
Knowledgebase.

Has anyone Information about what has changed and needs to be reconfigured
so that this VPN works again?

Thank you.

best regards
