Hello all. I explain the situation. I have a router with external IP and Im making NAT to 192.168.0.100 (ispconfig server ip) All ports are open without problem, but, configuring thinks I made something wrong. on ISPConfig ip address i have: 192.168.0.100 on hostname: mail.domain.com (i have the good domain) The problem i think is related with hostname/ip/ispconfiguration. mail.domain.com its a PTR hostname to the EXTERNAL IP off course. In hosts y add 192.168.0.100 mail.domain.com mail but i cant connect to: https://externalip:81 https://mail.domain.com:81 http://externalip and domain:81 <-- getting This IP address is shared. For access to the web site which you look for, enter its address instead of its IP. For questions or problems please contact the server administrator The other stange think is that i have a XP machine on LAN 192.168.0.XXX address (DMZ) and if i type on browser https://192.168.0.100:81 (lan) i can enter perfectly to ispconfig. Thanks for helping me. Regards. gabrielcz
