shorewall and DHCP requests

[thecooptoo]

ive got my wireless NW configured like this


www--CAT5-- eth0-router
___________ router--eth1-----192.168.0.x by DHCP)

one of the clients has the wireless AP

-CAT5----eth0--(192.168.0.8)client
___________ client(192.168.1.1)---wlan0---wireless client(192.168.1.x)-WinXP

and I use shorewall to pass all the stuff from wlan0->eth0 where it then goes to the router -->www


currently the wireless IPs are static

I'd like to browse shares across the subnets
I think id need a WINS server if I left the IPs as they are

If they were all on the same subnet (192.168.0.x) it would be easier ( wouldnt it?)

How do i pass the DHCP requests in shorewall from wlan0 (defined as loc) to net0 (defined as net in shorewall/interfaces)

Well, as far as i know you should create a rule in shorewall which tells it to allow the DHCP requests to pass from net interface to the wifi interface. DHCP requests are made through ports 67 and 68 UDP (if not mistaken). Only if your router is not RFC-1542 compliant you should install a DHCP Relay Agent in the other subnet (but if your router is a linux-box it´s no problem at all! ).

About the browsing stuff, installing a WINS Server would help you if you had machines which are Windows 98 or below, since from Windows 98 and above M$ started to rely on DNS name resolution instead of NETBIOS. But it helps to have a WINS Server if you configure your TCP/IP in Windows to use NETBIOS over TCP/IP and if the resolution method is primarily NETBIOS and not DNS and if you configure your network card with a WINS server address.

But, as you said, configuring everything in the same subnet is easier! And to have the browsing question solved as a charm, configuring all the computers to the same workgroup helps a lot, since windows broadcast all computers in the same workgroup if it is not configured to use a WINS Server.

Note: just to clarify your mind abou WINS: all windows clients are configured primarily to use broadcasts to resolve name if no WINS Server is configured and if a WINS Server is configured they first try to query the server, if not succesfull they will broadcast.

Hope that helps!
