Client Router/Free WiFi Hotspot/Port Forward?

Hello... I have setup an ENH200 in client-router mode and have successfully established a link between my home network and a nearby free wifi site. I have a WRT54GS behind the ENH200 which is providing access for my internal network.

The ENH200 ip is set at 192.168.1.1, and the WAN side gets it's ip from the DHCP server on the free site. I also have DHCP enabled for the ENH200 LAN side. The ENH200 LAN side is connected to to the WAN port of my WRT54GS, and the ENH200 is assigning a 192.168.1.2xx ip to the WRT54GS WAN port.

The WRT54GS ip is set at 192.168.2.1, and the LAN side of the WRT54GS is setup as a DHCP server that assigns my home net ip's in the 192.168.2.2xx range.

With this setup, all seems to work fine for basic networking and internet access... except when I try to run server software on one of the internal machines (192.168.2.201 - static). The issue is that I cannot access the server machine by port forwarding the ports that I need on either the ENH200 or the WRT54GS, or both (the server software requires forwarding of ports 2000-2003 when the server computer is behind a router).

When I connect the WRT54GS router between the server and a cable modem internet connection, I have no problem. But, when I add the ENH200 (in place of the cable modem) and try to go wireless via the free hotspot, it does not work.

What am I doing wrong with my current setup that is preventing me from accessing the internal server ports?

Thanks in advance for any help!!!

Wow! Over 100 views and nobody is able to offer me any insight! That really surprises me considering how "wifi smart" everyone usually is on this forum!!

Well...anyway... after putting "Engenius" or "WiFi port forwarding" into just about every search engine I could find on the web, I may have come up with a potential solution...

It looks like I will need to open the LAN side of the ENH200 by enabling DMZ for the ip address assigned to that port (assigned from the ENH200's DHCP server); and, then, set up the router to port forward to the server machine's ip (as normal).

It's my understanding that in this setup, the ENH200 should allow everything to pass thru it's LAN side and onto the WAN side of the router. At the router, the standard port forwarding setup will do the rest!

I will try this tonight when I get home, but I was hoping that maybe somebody could offer me an opinion as to whether or not this may actually be a likely solution - before I get home and spend hours messing with it again!

So... what say ye?

Many Thanks to all who reply!!!
