CLOSED: pfSense to replace WatchGuard SOHO 6

[rickh925]

The WatchGuard 6 FW appliance died today at one of my clients. I replaced it with a backup pfSense ALIX unit. Internet comms are good. Only problem is that I can't get the IPSEC tunnel to go through Phase 2 with the remote office.

I'm on pfSense 2.1.3.

I have all of the settings from the old FW, but it seems to be getting tripped up on the Proposal. I have Phase 1 set to Default Policy Generation and Obey for the Proposal Checking. The other office is managed by another IT guy so I need to do some coordination. I can't remember what device they have up there, but think it is a newer model WatchGuard device. The log looks like it is at least communicating, but failing in the Proposal selection.

From the IPsec log with some messages removed since it is pretty long. (1.1.1.1 is the remote site and 2.2.2.2 is my local site):

can you advise what's on the other end (your remote site) is it a pfsense also, i think you have a misconfiguration on your ipsec

[rickh925]

The other end is a Sonicwall TZ 200. I ordered a Sonicwall TZ 205 to replace the WatchGuard as the client didn't want to pay for me to troubleshoot this connection.

Anyway, the IPSec tunnel is intermittent. In fact, it is up most of the time EXCEPT when someone tries to connect across it. I have another client that is having trouble with OpenVPN and both are running across BrightHouse. I am starting to wonder if there is an MTU issue. I need to drop the MTU to 1300 and see if that helps.

NO-PROPOSAL-CHOSEN means the remote end is telling you it has nothing matching your P1 settings. Many times a wrong local or remote IP for the outside of the tunnel. Could potentially be any number of things in the P1. Unless somehow it stops complaining about that and negotiates successfully, you're not getting to the point where dropping large packets across the VPN would matter. If you can't ping across at default ping sizes, that's not the issue.
