I'm trying to set up a site-to-site VPN tunnel with an outside company from a PA-4050 on our side to a Cisco 3925 ISR. We can't can't get phase 1 to come up, though we're confident that the relevant settings (PSK, encryption, etc..) match up. We've tried different encryption settings, but the connection just times out on both ends. Before I go too crazy with it, I'm wondering if anyone has any experience going from a PA to a Cisco ISR, and if there is a trick, or if they just don't work together.
Thanks for any insight you might have.
There are no special tricks for the Phase 1 to come up, only for Phase2- If you are not using VTI interfaces on the cisco router, i.e route based VPN, you must configure proxy-ids on the PAN device. Can you also look at the phase1 logs on the cisco side? "debug crypto isakmp" ?
That's as I figured, but I thought I'd ask. This is a policy-based VPN, so I do have the proxy IDs configured. But as you say, that should only affect phase 2. I don't have access to the Cisco, but it's a good idea to ask them to run "debug crypto isakmp". Chances are we're just mismatched on something. Because we're in different time zones I wanted to make sure I wasn't running into an incompatibility before we spend a lot of time on the phone digging too much into the configs. Thanks.
