All ports are closed in my Linksys RV042 router-How to enable them?
Posted on 2008-06-24
Hi. I've been spending days to find a solution for this.
After we upgraded from DSL to T1(although this might not be a direct cause..), all ports in Linksys RV042 are not working for remote access from outside, for example port 5631 for pcAnywhere and 3389 for RDP. The router has the exactly same setting as before. The only addition from previous DSL is a CISCO 1841 router that sends WAN line to the RV042. (CISCO 1841 is an ATT managed router, which means I don't have access to it). RV042 works as a DHCP server for Win 2003 server with active directory.
I even directly single-connected RV042 to our Win 2003 server, and tried telnet -> open 192.168.1.1 in CMD, but connection fails. I first need to enable 5631 for pcAnywhere and eventually 443 for quickVPN as soon as possible. I don't understand why port 5631 which had been working for years stopped working suddenly. Would the new IP address or DNS from T1 be a source of the problem?
Any comment would be welcomed. Thanks.
