MultiWAN Fragmenting packets

TLP

Hello, after applying multiwan on my production server I started getting much packet drops because fragmentation, even my OpenVPN connections was getting dropped

after removing the multiwan it all started working normally again

Is there any know issues about this??

Thanks

What type of WANs? Cable? DSL? How many? Are you doing MLPPP?

TLP

2 Fibers, from different ISPs

but after adding the second wan, even the connection to the pfsense from the lan interface get compromised

Multi-WAN has no relation to fragmentation at all. In fact the firewall will never fragment packets. What's the actual problem and why do you think it's fragmentation?

The problem is, after activating my second wan all my openvpn clients get random disconnects, I attached 2 prints screens, one with just one wan and other with 2 wans

The fragmentation error I noticied because after activating the second wan, I get about 15 logs per second of blocked packets because fragmentation
When I deactive the second wan, the fragmentation drops to about 1 per second
I am not sure if fragmentation is caused by this, but the only thing I noticied was this

And another thing I noticied is after disabling everything related with the second wan, the openvpn drops still occurs, I didnt rebooted the system yet

edit: plus, i keep getting "503 - Service Not Available" accessing the pfsense
