in rc.conf:

eth0="eth0 192.168.123.30 netmask 255.255.255.0 broadcast 192.168.123.245 mtu 1492"

Sorry, but I didn't notice the typo in '1942', so I thought you wanted to set it higher than 1500. If I understand correctly your ethernetcard works only with mtu=1492?

Did you try

eth0="eth0 192.168.123.30 netmask 255.255.255.0 broadcast 192.168.123.245 mtu 1492"

in rc.conf? As far as I know those options are passed on to ifconfig, and in general the order of options doesn't matter much. Adding it to the end seems safest though.

How can I set MTU value in rc.config, if i use DHCP?

just chuck "ifconfig eth0 mtu 1492" in your /etc/rc.local.
