I'm not sure if this is relevant to your problem, but it might be.

Solaris boxes will act as routers themselves if they have 2 NICs by default. Could your Sun be trying to route, and conflicting with your other router?

To prevent this behavior, you use touch to create a file called /etc/notrouter. When the system finds that file on boot it does not do routing.

Check to see if that file is there, and create it then reboot if it isn't. Maybe that will help your situation.

NAME
defaultrouter - configuration file for default router(s) SYNOPSIS
/etc/defaultrouter DESCRIPTION
The /etc/defaultrouter file specifies a IPv4 host's default router(s). The format of the file is as follows: IP_address ... The /etc/defaultrouter file can contain the IP addresses or hostnames of one or more default routers, with each entry on its own line. If you use hostnames, each hostname must also be listed in the local /etc/hosts file, because no name services are running at the time that defaultrouter is read. Lines beginning with the ``#'' character are treated as comments. The default routes listed in this file replace those added by the kernel during diskless booting. An empty /etc/defaultrouter file will cause the default route added by the kernel to be deleted. Use of a default route, whether received from a DHCP server or from /etc/defaultrouter, prevents a machine from acting as an IPv4 router. You can use routeadm(1M) to override this behavior. FILES
/etc/defaultrouter Configuration file containing the hostnames or IP addresses of one or more default routers. SEE ALSO
