hi i've installed a suse 7.2. this one will be our router and firewall. first of all. the box has 3 NIC's. and the problem is - i cannot access everything from the boxes behind the router... :-(((. on next monday everything need to work... ip's are examples: eth0: official ip address - 213.14.46.4, gateway is 213.14.46.1, subnetmask 255.255.255.248 - 6 ip's possible eth1: official ip address - 217.10.0.46, subnetmask 255.255.255.240 - 14 ip's possible eth2: official ip address - 217.10.0.62, subnetmask 255.255.255.240 - 14 ip's possible now - if i'm on the linux box (router) with ip 213.14.46.4. i can ping the hole world and reach servers in the world... i can ping the ip's in eth1 and eth2. and the hosts behind eth1 (i haven't tested behind eth2 - but schould work, too). now the problem... i cannot access the world from (DMZ - behind eth1). there is a box with ip 217.10.0.34. on this box i can ping the eth1 (the gateway i defined for this net - 217.10.0.46). BUT i cannot reach gateway is 213.14.46.1 or any other host behind eth0 (internet). i've stoped for testing my susefirewall2 (but there was no drops befor or something else) and activated the ip_forwarding with echo "1" > /proc/sys/net/ipv4/ip_forward - but it isn't working too! are you able to explain me what to do to solve my problems? is it possible that my ISP dosn't route my networks correctly? now i'm at home and i've done a tracert from here to the networks. first of all i ping and tracert to 213.14.46.4. this will work. now i have ping and tracert to of 217.10.0.34... the way the tracert goes is different... inside the ISP net the tracert goes another way!?!?! if you can please describe me shortly what need to be done in principle to get a suse working as a router. am i right about the way above? are the only things to do setting up the NIC's with the official ip addresses and activate ip_forwarding ore is there anything additional to do?! absolutly confused... PLEASE HELP Alex
