[ale] [OT] Networking Question about switches

[George Allen]

It sounds like your setup is:

[ISP?]
|
[Router?]
Gw:192.168.0.254
|
[Switch A] 192.168.0.0/24
|
igb0 192.168.0.2
[Server]
igb1 192.168.1.2
|
[Switch B] 192.168.1.0/24
|
[?]

Questions?
- doesn't your gateway for *.1.0/24 need to be on *.1.0?
- your switches are not physically connected?
- is LAN B (192.168.1.0/24) a closed network? Is it being forwarded by the
server to 192.168.0.0?

Please send the log you mentioned, with
grep GATEWAY_ENABLE /etc/rc.conf
ifconfig
netstat -r
