Can't connect remotely to my network

Hi everyone!
I'm working for someone whose network was set like this:
DSL modem (westell 2200, which I believe it works as a router too) connected to a Router (Linksys BEFSR81) connected to a switch with around 12 PCs. OK what he needs is to install Radmin to access remotely from his house to an specific pc. I know how to do the Radmin part, and port forward directly to the Pc we want by the port 4899 etc. that is ok. I've done that more than once. Now for that to work better we asked his company (bellsouth) to get him Static IP. They set it, I set the router to optain an IP automaticly (as I think it should be, cause they will give him the same IP everytime) The problem is that after this (and maybe some misconfiguration from my part) I haven't been able to connect to this PC or the network itself. There is internet and I can use Radmin from there to connect to his house, but not in the other way. I also cannot connet remotely to the router, in which I enabled that option despite the IP hasn't changed. What I did remember I did was to change an option inside the router that gave me to choose between router and gateway. I changed it to router (it was in gateway mode) without knowing what I was doing (I still don't know what is that), but that was the only way I could get the network connected to internet.
Now everything works great (internet, etc) but I can't access this network remotely despite at first it was possible when the IP wasn't static. I'm not sure what to do. I'm gong to try setting the modem to full bridge and if it doesn't work I'm gonna take the router out of the connection, as the modem seems to be a router too, though in this case instead of port fowarding I think I'm going to use IP passthrough. Will this give a good result too? I haven't done it before I'm using pure logic
Also for your info I set all the internal IP manually and disabled the DHCP of the router to get static (internal) IP's for the pcs. I need smart suggestions from you guys, anything wil be welcome, I'm driving myself crazy!!
Tell me something! please

!

Is the Westell Modem acting as a router as well or is it in bridge mode? If the Westell Modem is not in bridge mode it also has built in router functionality and probably needs to have the port forwarded.

If that modem works as router too, then remove that Linksys router and make your configuration on that modem router only with port forwarding. Try and see whether it works. Also you could check whether there is firewall blocking issue on PC and modem router. Hope helps..
