[SOLVED] Gateway stopped working after upgrade to 16.7

[lukepower]

Hi Guys,
I did the upgrade to 16.7 yesterday and it all went smoothly - apparently, at least.
I found out that a part of our network lost internet access since the upgrade, and exactly this part (the Guest WLAN) is using a different interface to access the internet. Basically, I am using an PPPoE connection as the main WAN connection, and a router (located at 192.168.0.6) as a second connection for the Guest WLAN.

I did several tests, and it seems that OPNsense is unable to use that router to access the internet. I currently have it configured as a gateway and didn't change anything, so I am unsure about what might be wrong. Any hints?

Thanks
Lukas

Hi Lukas,

Can you check if your guest WLAN is still available in the firewall rule selection? if not, the fix is simple. save the wlan interface and reboot or reload your firewall rules.

Hi Ad,
actually I had to try several things to get it back working. Seems that I had to both reboot the DSL router as well as OPNsense. It worked flawlessy for about 24 hours and now it's down again. The funny thing is that OPNsense detects a "link down" situation even if it is working. Only a reboot of the upstream router helps here.

Hi Lukas,

Maybe the gateway doesn't respond to ping for some time, you could try to disable gateway monitoring (system -> gateways) and see if your connection remains stable.

Best regards,

Hi Ad,

it seems to work now well. Maybe it was really only a matter of rebooting the system.
Thanks
