Title: (Multiwan) Short hickup when Tier2 goes down
Post by: shadesh on April 08, 2020, 10:37:59 AM
Howdy Folks!

I have a good running MultiWANSetup (Tier1 VDSL and Tier2 LTE) running at my homeoffice but i noticed some strange behavior when the Tier2 WAN members goes down (LTE in germany has some strange forced separation after 24h). My internet connectivity goes down for just a few seconds.

system.log:

Apr  7 12:55:00 gw opnsense: /usr/local/etc/rc.filter_configure: Ignore down inet gateways : LTE_PPP

gateway.log:

For me it looks like that OPNSense is flushing the state table and recreating it multiple times, one time after Tier2 goes down and one time when Tier2 is coming back online. Is there a way to ignore the state change on the non active Tier2 gateway?

Thanks in advance!
