fuzzylizard Posted March 10, 2004 Report Share Posted March 10, 2004 I am having a problem with almost any persistant network connection and I am not sure if it is because of the firewall I have or because of my ISP. To begin with, a little background. My ISP is Bell Sympatico and I have their High Speed Edition (HSE) which is a standard DSL connection running at 3Mbps download. The firewall that I have is a Linksys BEFSX41 - Instant Broadband™EtherFast®Cable/DSL Firewall Router with 4-Port Switch/VPN End. Quite a nice little unit. Now for the details of the problem: Any time I open an ssh connection, the connection will eventually get cut-off. Now, before you tell me that the problem lies with the ssh server that I am connecting to, here are some facts. The ssh server belongs to several different servers at my university. Before going with Sympatico HSE, I was with Rogers Highspeed (cable) and could leave SSH connected for days. I have talked with other students since changing to Sympatico and they assure me that they are able to be connected to school via SSH for days. I did purchase the firewall last november, before that I was using Smoothwall. However, I am certain that this problem existed even with that firewall in place. So, the question is twofold then: (1) is there anyway that this is a function of the firewall? (2) is there anyone who is with Sympatico HSE that is having the same or similiar problems? Just to clarify, this is not a Linux problem as I have the same problems regardless of OS. I also have the same problem with ftp and, from the looks of things, any tcp based connection. UDP based streaming connections do not seem to have this problem. Although I have not fully tested this to ensure that this division does exist between the protocols. Anyone have any ideas?

fuzzylizard Posted March 10, 2004 Author Report Share Posted March 10, 2004 I have done two things and the problem seems to have gone away. The first was to update the firmware of the router/firewall and the second was to increase the keep alive time to 180 secs. So far I have been able to keep an SSH connection active for the last 3 hours. This is a huge increase versus the 1-2minutes that I use to be able to get.
