OK - with this setup, you are going to want the default route on the
Samba machine to go through eth0 using the same gateway as the Nix
Router uses, and not using 192.168.1.1 as the gateway. running
through the other way is going to cause problems. Yes, you can
access the Internet the way you have it now, but packets will come
in on eth0, and the reply will travel out eth1, and through the Nix
router instead of going back out eth0. Depending on how your router
is set up, they may not make it to the Internet. The router may eat
them. Also, with the router is doing NAT, the reply will look like
it came from 12.73.1.180 instead of 12.73.1.185, so it will may get
rejected by the firewall on the other end.

You may want to look at the logs on the nix router, and see how it
is handling your packets. Depending on the logging level, it is
probably dropping a lot of Samba trafic coming from the Samba
machine trying to get to the Internet.
