hi, i'm quite new to admin world, I've setup a gateway between 2 network branchs, and i don't get where my error is.... the branch one sees the branch 2 but the branch 2 doesn't see the branch one.... my rules mustn't be right for the 2 ways... but why ??? the system is a SuSE 7.0 on a intel pc. #!/bin/sh echo 1 > /proc/sys/net/ipv4/ip_forward /sbin/ipchains -F input /sbin/ipchains -F output /sbin/ipchains -F forward /sbin/ipchains -P input ACCEPT /sbin/ipchains -P output ACCEPT /sbin/ipchains -P forward DENY /sbin/ipchains -A forward -j MASQ -s my.sub.net.one/24 -d 0.0.0.0/0 /sbin/ipchains -A forward -j MASQ -s my.sub.net.two/24 -d 0.0.0.0/0 I want both network to see each other fully... I start to flush all existing rules... thenmy default policies is to accept input and output whithout questionning and to forward from sub1 to everywhere and from sub2 to everywhere.... what's wrong with this ? why subnet2 doesn't see subnet 1 ?.... TIA.. Philip
