This has been seen before, and is easy to fix if my assumption is correct.

Try adding this to your firewall:
$ iptables -A FORWARD -p tcp --dports auth -j REJECT \
         --reject-with tcp-reset

This will "reject" any packet destined for the auth port.
My guess is that the Solaris box does not have a auth deamon running, 
and therefore Linux clients will "hang" while waiting for an answer from 
the port.
