It sounds like you may have misconfigured one of your interfaces. The output of `ifconfig`, `netstat -rn`, and `grep ^ifconfig /etc/rc.conf` would be helpful in diagnosing your issue. Also, I noticed you say your wired interface is a /28 but then state it’s configured as a /24. Perhaps this is your issue? Matt
