Hi, my configuration are: - ADSL-WAG354G, 18.104.22.168, dyndns.org are active - Router-WRT54G, Internet 192.168.0.101, Local 192.168.1.1 - Client WXP, 192.168.1.100 - Server Linux/CentOS, 192.168.1.10 -> Virtual Server over tun/tap Linux/P390 192.168.10.1 On the WRT54G-Setup-Menu - Applications&Gaming - Port Range Forward there is the "IP Address" column only with a fixed mask ...__ on the web gui. If I try to reach the Linux/P390 on 192.168.10.1, so I need to have a setup mask like ..__.__ on the Port Range Forward. If I'm working Intranet, so I can trick with route from the client WXP as "route -add 192.168.10.1 mask 255.255.255.0 192.168.1.10 metric 1" to reach e.g. HTTP-Server on the Linux/P390, but if I'm comming from WAN (e.g. dyndns.org) I need a port forwarding not only for 192.168.1.10 I need as well for 192.168.10.1 Is there a chance to force the web gui setup mask on WRT54G with an other firmware version or an other solution to fixed that kind of problem. Thanks for your help!
