> Dear Debian-users
> I'm hoping for some pointers or help on how to set up a combined WAN and
> LAN+WLAN network. The situation is as follows:
> A Linux box with two interfaces eth0 and eth1, used as a gateway. eth0
> is connected to the WAN ISP with DHCP using an ADSL modem. The second
> interface eth1 for LAN is connected to an 8 port switch, static
> interface 192.168.0.x. All connected computers to ehh1 are statically
> defined. Now I have connected one of the ports of the switch to a
> Wireless router configured for an ip-address of netnask
> The WLAN router has in addition to the wireless
> interface, one upstream and four RJ45 connections.
> The WLAN router internet settings are:
> Static IP address, 192.168.0.y, same subnet mask as above. Gateway is
> the Linux box, 192.168.0.x, and DNS addresses are supplied by the WAN
> ISP.
> With this setting I can connect (both to the gateway and internet) using
> the wireless or one of the wireline interfaces from e.g. a laptop with
> DHCP supplied by the WLAN router. The resolv.conf contains 'nameserver
>' and this works for both laptop interfaces. Addresses
> assigned are to
> Some problems still arise:
> - I cannot connect from the Linux box to the computers connected via the
> switch to the router. How to accomplish that?
> - Another solution is to connect the upstream port of the router
> directly to eth0 and obtain dynamic addresses to the LAN and WLAN
> computers from the router. I think the problem still remains: How to

> boxes?
