RV340 VPN Issue

ServicePros
Level 1
Level 1

Hey Everyone,

 

I'll keep this short: I'm trying to establish a VPN connection between this RV340 and a Fortinet. No matter what settings I try, I can't seem to get them to talk to each other. Here's the current logs, but we have tried a bunch of things like IKEv1, now PSK passwords, different encryption etc. It really doesn't seem to matter. Any ideas on this one?

Hey Everyone,

 

Got it to work. We were going back and fourth changing settings on both sides of the VPN. At some point I noticed that even if I changed Ip addresses or whatever setting, the error logs looked the same. I actually went in and deleted the both the site to site and IPsec profiles and rebuilt them...came right online. It was almost like the profile was corrupt from all the changes. Hope this helps someone!
