[rescue] Solaris as a gateway router

[Curtis H. Wilbar Jr.]

Assuming you have all the ethernet ports configured correctly in
Solaris, and assuming they are all good... check your netmasks,
disable ipfilter and retest to make sure it doesn't have to do
with the ipfilter rules.

Depending on the subnets you are using, if your using multiple 10.X
subnets and you don't set the netmask, Solaris will assign 255.0.0.0
as the netmask.  Check your netstat -r output to see where different
stuff will go, check your netmasks with ifconfig.

Depending on your network config as well, keep in mind that Solaris will
use the same mac address for all ethernet interfaces.  Depending on how
your network is arranged (multiple ethernet ports on the same segment)
this will possibly make things unhappy as well.  If this is a problem
with your network, change the mac address with ifconfig for those
interfaces.
