Hello all,
I have a very weird issue concerning PAT.
I have an ASA5505 with ASA8.2(2) running. The outside interface is on "dhcp setroute" mode and receives an IP address from our ISP. The inside interface is connected to a switch with desktops connected it. I have specified a NAT rule which allows the inside network to NAT over the outside interface and I have specified an ACL on the inside interface which allows all incoming traffic to the outside world. This works perfectly so far. Every host has internet connection.
Here comes the tricky part where I'm already stuck on for a day. There is one host which runs a Teamspeak2 server on port 4444. So in ASDM, I created a static NAT rule specifying the inside adres of the host to be translated over the outside interface using PAT UDP 4444. I created an ACL on the outside interface specifying that "any" incoming to destination "outside" on UDP/4444 should be allowed. However, no one is able to access my Teamspeak2 server, including myself. I can only connect to it on the internal address, so the server is actually running!
I also tried the same with RDP. No success either. There is no (Windows) firewall running on the end hosts. Please see my config below and the attached screenshots. I hope someone can help me out.
