Linksys router behind a PIX 501 causing applications to fail?
Posted on 2006-05-02
I didn't set this up, but will this configuration work or cause problems?

Single static public ip from dsl provider; public ip of X.X.X.116 port forwards to server running Windows 2003 Small Business Server with Exchange 2003. The server is assigned an inside address of 192.168.35.3. It acts as a file server with several shares and as a domain controller.
The Linksys is assigned an ip address of 192.168.35.5 and has a local address of 192.168.1.1. Default gateway on the Linksys is 192.168.35.1 (Pix). The Linksys WAN port is plugged into the Pix. Client pc's are plugged into the Linksys and the Linksys acts as a DHCP server handing out ips on the 192.168.1.x network
Devices behind Linksys seem to access the server without restriction. The server cannot access devices behind the Linksys.
Will this configuration work? The reason I ask is an application running on the desktop and laptop which uses an Access database on the server that fails periodically. Word documents and Excel spreadsheets on the server sometimes stop responding, and clients that have drives mapped to the server lose their connection.
Wouldn't a better configuration be to use a cross-over cable from the one of the switch ports on the Linksys to the Pix, leave the WAN port on the Linksys empty, and stop the dhcp process on the Linksys? That way every device is using the same network address (192.168.35.x) and the Linksys acts as a wireless bridge.
There are a number of significant problems that are occurring with various applications. Could the above configuration be causing this?
Thoughts and replies are appreciated, the quicker, the better.
