Hi there, I've build a router for my wireless users which is about 50 customers. Now each user has it's own subnet which I all added onto one network card. How good idea is it to do something like this and is there a better way off doing this. I'm somewhat new to this whole netfiler / ip routing thing. This is what my routing table looks like at the moment. I've basically added virtual interfaces for each subnet on one network card. Example : eth1:0 , eth1:1, eth1:2 Kind Regards Stephan 10.0.1.168 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.172 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.160 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.164 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.184 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.188 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.176 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.180 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.136 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.140 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.128 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.132 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.152 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.156 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.148 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.232 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.236 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.224 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.228 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.248 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.252 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.240 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.244 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.200 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.204 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.192 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.196 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.216 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.208 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.212 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.44 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.40 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.36 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.32 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.60 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.56 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.52 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.48 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.12 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.8 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.4 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.0 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.28 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.24 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.20 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.16 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.108 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.104 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.96 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.124 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.120 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.116 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.112 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.76 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.72 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.68 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.64 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.92 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.88 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.84 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.1.80 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.2.240 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.2.244 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.2.248 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.2.228 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.2.232 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.2.236 0.0.0.0 255.255.255.252 U 0 0 0 eth1 10.0.5.0 0.0.0.0 255.255.255.248 U 0 0 0 eth1 10.0.5.24 10.0.1.26 255.255.255.248 UG 0 0 0 eth1 10.0.5.16 0.0.0.0 255.255.255.248 U 0 0 0 eth1 10.0.5.40 0.0.0.0 255.255.255.248 U 0 0 0 eth1 10.0.5.56 0.0.0.0 255.255.255.248 U 0 0 0 eth1 10.0.0.0 0.0.0.0 255.255.255.240 U 0 0 0 eth1 10.1.0.0 0.0.0.0 255.255.255.224 U 0 0 0 eth1 10.2.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth2 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo 0.0.0.0 217.10.176.149 0.0.0.0 UG 0 0 0 eth0
