Hello I have a linux 2.4.20 firewall running iptables 1.2.7a with ip_conntrack_h323 and ip_nat_h323 installed and Netmeeting running in both ends, inside the LAN and in the Internet. Sometime appears on screen the following error six times: H.323_NAT: partial packet 0/6 in 0/0 H.323_NAT: partial packet 0/6 in 0/0 H.323_NAT: partial packet 0/6 in 0/0 H.323_NAT: partial packet 0/6 in 0/0 H.323_NAT: partial packet 0/6 in 0/0 H.323_NAT: partial packet 0/6 in 0/0 and in syslog twice: /var/log/syslog:Mar 24 21:32:58 firewall kernel: H.323_NAT: partial packet 0/6 in 0/0 /var/log/syslog:Mar 24 21:36:08 firewall kernel: H.323_NAT: partial packet 0/6 in 0/0 I searched in Google but I found only 9 occurences but in italian language. Does someone know, what causes this error? Regards Herbert
