Hi all, We are currently testing NetFilter on Linux Slackware 9.0. We have configured our netfilter to make SNAT and DNAT. Some issues have been observed while configuring SNAT to allow ICMP. When implemented this rule, it takes some time before icmp being able to work. When rebooting the NetFilter box, the same strange behaviour is occurring. Howewer all other SNAT/DNAT rules implemented are working immediately, It' takes about 5 minutes until ICMP is working again. It's a very strange behaviour, isn't it? Please find the rule for ICMP: Iptables -A POSTROUTING -p icmp -s 192.168.1.42 -d 172.19.92.0/255.255.255.0 -j SNAT --to-source 172.19.93.200 Any help would be appreciated.
