Port Forwarding with BEFSR41

[bnosbod]

I have a BEFSR41 setup in an office with a subnet of 192.168.10.1 and have loaded an application on one of the pc's on this subnet that needs to acces a server on the other side of a BEFSR41 router with a subnet of 10.0.0.1. I configured both routers for port forwarding as well as port triggering and still cannot get the application to "see" the server. The ports in question are 161, 3670 and 80.

Any ideas?

Thanks,

Bill D.

Let me see if I've got this right -

The WAN side of Linky has an ip address of 10.0.0.XXX and the LAN side of Linky has an ip address of 192.168.10.1
The application is on a pc with the ip address of 192.168.10.XXX.
The information required by the app is on a server on the WAN side of Linky with the ip address of 10.0.0.XXX

With this scenario, no port forwarding is required for either router. The app just needs to know how to get to the server. The server does not need access to the PC, so no forwarding is required on the Linky. The Linky (and consequently the pc) is inside the main router (10.0.0.1), so no forwarding is required for the main router.

How does the app access the info on the server? - Windows shares, http, something else? By name, By ip address, mapped drive letter? From the PC, can you ping the server at 10.0.0.xxx?

The application in question is Ricoh's ScanRouter software for network scannibg. The application resides on a pc and contacts the I\O device (which is a Ricoh Aficio 1035 MFP) vis FTP on port 3670 SNMP port 161 as well as random ftp ports from 1024-65535 for data. Port 80 is also utilized.

There's a bunch of info about this in the knowledge base /faq section of Richo's web site. Which segment of the lan is the I/O device on and in which direction are you having problems communicating?

The I/O device is on subnet 10.0.0.0. The pc with the applictaion is on 192.168.10.0. The I/O device can't connect to the pc to update the address book, and the pc can't find the I/O device. I did include an entry in the hosts file for the I/O device. I can print form the pc to the I/O device as well as ping the I/O device. When I run netstat I can see port 3670 as listening on the pc.

The easist thing may be to put the 192.168.10.XXX pc in the Linksys DMZ. Since this is still behind another router (10.0.0.1), it shouldn't pose any security risks. To do this, go to the router admin, advanced section, DMZ host tab and add the pc's ip address.
