I'm running monowall version 1.231 (and several other versions). I often see
MTU problems - especially when using Captive portal and a bridged wireless
network on the OPT1 interface.
Most of the time the connectivity problems can be solved by setting the MTU
to 1300 for all interfaces. I have not found the underlying reasons for the
problems - but i believe it has something to do with missing ICMP source
A minute ago i saw this setting under status.php
"net.inet.ip.sendsourcequench: 0". From the top of my head... should this
setting not be "1"?
