WireGuard not working ipv4 after update to opnsense 24.7.5

[Bob.Dig]

To bad. I think it was worth the try. But again, no need for a gateway on your phone over WireGuard in OPNsense. But I resign from this thread now. Good luck!

ok, thanks for your help Bob.Dig

1. MTU seems awful high.  mine is 1300 and I get full speeds.  almost 500Mb for my wan fiber line
2.  I have disable routes checked for all of my tunnels

Last one, try 1280 as MTU and also try disabling routes, it shouldn't be needed in this case.
Also don't use keep alive on the OPNsense, only do that on your Phone.

Tried this also, same resulting, have to hit apply on the gateway page to get it to work. Thanks for the help so far!

System - settings - general.

Very bottom what is allow gateway switching set too? Mine is unchecked

Firewall - settings - advanced - skip rules is unchecked for me

[RamSense]

Hi again, just checked. gateway switching unchecked also, and skip rules unchecked too.

N.B. I noticed also that when I make a change in the opnsense wireguard instances or peer config and hit apply, I need to go to gateway-configuration and hit apply there for ipv4 and  ipv6 to be back up. So my old situation (on opnsense 24.7.4) trick of interface, off safe, and on safe - looks to be merged to the trick of going to -gateway-configuration and hit apply. But I believe there are related to the underlying issue I see/have.

just to confirm here.

mine does similar.  but after the probe interval time has passed, it normally does come back online

yours never ever comes back until you click resave?

my probe interval is set to 15 seconds

[RamSense]

correct, I have to hit apply on gateways for it to come back
