Strange Behavior (Drops during transfers)
-
Hi all,
I search and did not find anything about this so here it is...
I have 4 WireGuard VPN's setup in my system. 3 of them work perfect. The 4th one use to work perfect but now drops the connection.
About a month ago now I did some updates on the servers at my client. All went well. I did not update pfsense as it was not needed and it is already up-to-date.
Then I started to notice my backups failing over the VPN. and here is where I find the behavior odd... The VPN only goes down during the backup. It will backup for about 4-5 minutes then the VPN goes offline and can't handshake for about 15 minutes.
I have no clue what to try. I have re-installed the VPN package on both PFsense machines and that did nothing.
My Setup: All VPN's are pfsense wireguard to pfsense wireguard. All have static IP's. When it was working and during the 4-5 minutes it backs up it will transfer at 600Mb's so the speed is great when it worked.
Can someone point me in the right direction? I would provide logs but can't seem to find any for wireguard.

@jrichmond are all pfsense have a public IP on the WAN?
Wondering if there is a double NAT or CGNAT in play. -
@michmoor No double nat. Both have a public IP.
-
@jrichmond Hmm strange. Ive never encountered this issue before.
You got MultiWAN?
I checked redmine i dont see anything similar to what you are describing. -
@michmoor I Do have multiple WAN connections. I have the wireguard only using one WAN connection though.
