Hi Frank, Usually whenever I get these kinda problems I delete the rule and set it again, which always seems to work. Make sure you use the "auto add firewall rule" when creating the NAT rule, failure to do so can cause problems I know from experience. However, it that doesn't work I'd start looking in the other end first. Does port 2023 work internally? Is there a firewall in use at the unix server side? Can you access canyouseeme.org from the unix server and see if it actually does work and there's something else all together? /Daniel Jokinen -----Ursprungligt meddelande----- Från: Frank Bello [mailto:[email protected]] Skickat: den 24 april 2013 03:16 Till: [email protected] Ämne: [m0n0wall] Port Forwarding problem on 2023 All, I've been testing the M0n0wall appliance in an ESX 3i host and have been very pleased with it. However I wonder if someone can help me find out how come a port/NAT forwarding rule that I'm trying to set for port 2023 is not working. The rule allows access to the outside TELNET clients to an internal UNIX server which is listening for TELNET connections on port 2023 I have setup forwarding rules for RDP on 3389 and for VMWARE client management on SSL and other private ports and it works perfectly. However when I tell it to forward 2023 it does not. And only in that rule. I have also tried to create another rule where the external port 23 will be forwarded to the internal 2023, but that does not work neither Following are the pages from my setup. Any help ? thanks in advance. F.
