I can get to my server on a LAN but not from WAN (router with Port
forwarding to Server)

I have 1 Server installation which I've been playing with...

Firewall Interface:
Custom eth0 for External,
Custom eth0 for Internal
Intel Ethernet eth-id-00.yy.12.23 Internal Zone

The New server is setup the same but I cannot access!

I've checked settings for allowed Serverice in Yast and Nows firewall
