If you have decided to do it with these commands, do not forget the other
UDP broadcasts which are automatically forwarded.
Have you also considered putting permanent static routes in the workstation
and server ?. Will the application allow this for communication ? If it does
, you do not have to touch the router.
Let us know how it turns out.
example:
ip helper address 10.2.2.2
no ip forward-protocol udp 69 !(this does not allow tftp broadcasts)

Subject: Re: NetBios forwarding (Addendum)
You're right, I do need that in my config. I had it in the first post, but
forgot to add it to the second one. These two lines should be in the second
version:
int s0
ip helper-address 10.2.2.2
int s1
ip helper-address 10.1.1.1
I think this would accomplish what I'm trying, but I'm wondering what any
downsides might be and if there is a better way.
