22.7 Legacy Series / Re: OPNsense 22.7_4: Loss of Network Connectivity
« on: September 07, 2022, 06:15:17 pm »
Hey there,
we just updated our firewall cluster to version 22.7.3_2 and also experienced connectivity problems. We have a multiwan setup with 3 different upstream providers. The firewall itself lost outbound connectivity.
We did some tcpdumping and saw that packets had an ip address of 0.0.0.0.
If we explicitly create snat rules on the wan interface to a public ip from the corresponding wan ip space, traffic works.
We cross checked with another setup, running with the 22.1 version and did not see this behaviour there, source ip was set to a correct address.
