Hi thanks jerry,
Almost there, just need clarification...
On the router, what should I use for the LAN network, like this or different?
(is that correct? It means the network does not include the higher ranges 172.18.96.xxx etc)
Should the router firewall settings be virtual server port 80 to 172.18.0.1??? or 172.18.???.??? What is the main IP address of the XS, I thought is was 172.18.0.1
To add a route on the XS, do you mean (and what are the ??/):
route add default gw 172.18.0.88 netmask 255.255.???.??? landbond0???

OK, I have that backwards your running the XS as is and you have added
the linksys with the ip address 172.18.0.88. The linksys is providing
the route to 192.168... The XS can't respond to anything from 192.168...
as there is no route back to 192.168. You can either add a route to
192.168... via 172.18.0.88, or add 172.18.0.88 as the default gateway,
on the XS.
