redirect an ip to an external ip/port
I have found a problem in my network with an external PC that needs to connect to a jabber server outside my network. Since a couple of weeks ago it no longers connect and I havent found the cause. My last resort is to manually redirect the traffic coming from that ip to jabber port to the jabber ip/port. Or, let the jabber client connect via squid, a solution which neither can make work.
Can somebody give me an idea about the required rules or configuration?
