Hello. I'm am looking in to using UDPTUNNEL to help me get some udp traffic from outside a firewall to the inside network. Specifically I have a windows box running an SNMP agent which forwards traps when a particular event occurs on the box. I've spoken to someone on the Cygwin mailing list who's advised me that udptunnel does indeed compile under cygwin. Assuming port 22 is open on the firewall from the machine outside to a particular IP inside I'd like to get ensure these SNMP traps are received by a management station inside. I have no control over the firewall and there is little likelyhood I can get the configuration changed. What I was hoping to do was create an SSH connection to a host inside the firewall and then redirect a local TCP port (on the machine outside the firewall) to a third machine (the management station) inside the firewall. The managment station would be running udptunnel in server mode. udptunnel on the machine outside the firewall would be configured in 'client' mode and would redirect UDP traffic to a local TCP address (which will be forwarded by SSH). Am I correctly understanding how udptunnel is supposed to work? Can someone give me the syntax for the 'client' and 'server' ends of udptunnel if I wanted to forward SNMP traps? I have done a search of the mailing lists and also on google but have not found much. A helping hand would be appreciated. Thanks in advance. PJ http://mobile.yahoo.com.au - Yahoo!
