Posted: Thu Nov 17, 2011 17:54 Post subject: Setting up Port Forward help
I'm trying to set up a port forward so that afp traffic (port 548) get's passed to my home server. I can access the afp server just fine on lan via the static dhcp addy I set for it (192.168.1.2), but I can't get to the server from wan (either addressable IP or dyndns, inadyn running fine on the Asus box). I always get a server time-out error. According to the router it should be forwarding traffic on port 548 to 192.168.1.2:548 but nmap does not show that as an open port and I can't seem to access it. There's no firewall on the server (I turned it off to check). Please help! Here's the output from nmap and from the router itself.

I'm testing the connection from work, not trying a loop. I'll bookmark that though in case I need to test at home.
Ok. It shows 548 is open from my connection (you hid your IP, but not the DNS):

Sounds like the connection/firewall at your work may be blocking it. _________________ (05/02/17) std - 31924
