Since you are using the rge driver, you might be getting bit by CR6686415.
http://bugs.opensolaris.org/view_bug.do?bug_id=6686415

The symptoms are that some packets work, more likely with small packets
like pings, but large packets might not work.  I've also had trouble not 
being
able to talk to systems on my LAN, but able to get to the internet.   
Try the
workaround in the CR.
