IP KVM and remote access

IP KVM and remote access

My environment consists of 17 IP KVM switches with about 8 expansion modules per switch.

All switches are on the same subnet. In the office, using the KVM Console viewer, all is fine.

When using a VPN connection (Cisco client) to the office, I am able to ping the switches and connect to the switches. I am UNABLE to connect to the servers though. I am able to telnet to the switch on port 2068 and 8192 which tells me the firewall is ok.
If I select a server and try to establish a connection, I get a timeout error after about 20 seconds.

Is there a way on the switch or software (using 2.5b client) in increase the timeout value? Is there any other setting/configuration we should look at?

Re: IP KVM and remote access

Did you get this to work? I am having the same problems. I have opened TCP ports: 2068, 8192, 3211, 161 but still no joy.

Please advise.

Re: IP KVM and remote access

I did a packet capture and discovered that the KVM client trys to make an initial connection on Port 3211 via UDP. Once connected, it uses TCP on 3211. The documentation does not cover this but I'm sure this is what will fix your problem. It did for me!

I see you opened 161, TCP as well. That port is for SNMP so you probably want that to be a UDP port as well.

Good luck!
