netbios / udp broadcast forwarding

[Langrdge]

I am trying to get this working so  I can join machines in one VLAN to our domain, where the domain controllers are in a different VLAN. Quite common.

I have enabled ip routing and ip broadcast forwarding a a global layer, and set ip broadcast forwarding at the vlan layer, however i still cannot join machines to the domain.

the commands I have used are as follows:

config

 ip routing

 ip udp-bcast-forward

end

config

 vlan xxx

 ip forward-protocol udp xxx.xxx.xxx.255 netbios-ns

 ip forward-protocol udp xxx.xxx.xxx.255 netbios-dgm

 ip forward-protocol udp xxx.xxx.xxx.255 dns

end

I would really appreciate some feedback on this and how people are doing this; other forwarding such as DHCP Helper addresses is working fine...

If anyone wants to trawl through our config files am happy to upload them but will leave off for now.

Thanks,

Shannon

The normal thing to do would be to set up a WINS server or two, if you are still using NETBIOS. Then have your DHCP server provide their addresses to clients.
