Dear list users, This is the config I have: Inet network: 195.144.47.112/29 RFC1918 network: 192.168.1.0/29 border gateway --- gate.belfin.ch --- IIS 5 http/https .113 eth0: .114 eth0: .2 eth1: .1 Portforwarding is set up on gate.belfin.ch (linux box) from .114 to .2 on ports 80 and 443. I can access http on .2, but I cannot access https. I don't think theres something wrong with my portforwarding config (see below). But there could be something wrong with the ssl certificate. Telnetting from .1 to .2:80 and .2:443 is no problem. Locally on .2 I can access to http but not to https. IE says server or DNS cannot be found. Seems like the port is being resetted by 192.168.1.2: iptraf screenshot for https after loading the web page: 195.144.47.114:443 212.254.96.227:10117 4 1136 CLOSED eth0 212.254.96.227:10117 195.144.47.114:443 7 557 CLOSED eth0 192.168.1.2:443 212.254.96.227:10117 4 1136 CLOSED eth1 212.254.96.227:10117 192.168.1.2:443 7 557 CLOSED eth1 iptraf screenshot for http after loading the web page: 212.254.96.227:10119 195.144.47.114:80 8 1719 --A- eth0 195.144.47.114:80 212.254.96.227:10119 5 1985 -PA- eth0 212.254.96.227:10119 192.168.1.2:80 8 1719 --A- eth1 192.168.1.2:80 212.254.96.227:10119 5 1985 -PA- eth1 Thank you any help.
