Hello list, I wish to use GnomeMeeting, for which I assume the only port that needs opening is 1720. Now, how can I forward all incoming traffic to port 1720 on the router, to one machine on the network that doesn't have a fixed IP (DHCP), but has name on the domain thanks to DDNS (ex : abox.mydomain.net). Another question regarding ip_conntrack. After 5 days of use, I get the following error in syslog : "ip_conntrack table full, dropping packet.". I then increased the value in /proc/sys/net/ipv4/ip_conntrack_max, from 3048 to 8192, but I think this is a quick fix that won't get me too far ... Is there a mean of flushing that table ? If not, how can I lower the TCP connection timeouts ? Thanks in advance. -- Open WebMail Project (http://openwebmail.org)
