Hello, I'm trying to setup my comp to do NAT. I've compiled all the necessary options into the kernel (2.4.18), turned on ip forwarding, and setup my iptables rules to forward all traffic. I've been trying to setup NAT on multiple OSs and had no success, which leads me to believe that this might be a hardware issue. I'm able to get an internet connection by plugging in my nics one at a time, but not with NAT. The cards I'm using are 2 D-link 530tx+, and 1 Realtek 8139. Any ideas what might be wrong? ---------------------information--------------------- ifconfig -a: eth0 Link encap:Ethernet HWaddr 00:50:BA:61:20:C1 inet addr:192.168.0.175 Bcast:192.168.0.255 Mask:255.255.255.0 UP BROADCAST NOTRAILERS RUNNING MULTICAST MTU:1500 Metric:1 RX packets:4345 errors:0 dropped:0 overruns:0 frame:0 TX packets:4885 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:2703357 (2.5 Mb) TX bytes:713218 (696.5 Kb) Interrupt:5 Base address:0xd000 eth1 Link encap:Ethernet HWaddr 00:50:BA:61:1E:DC inet addr:192.168.0.1 Bcast:192.168.0.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) Interrupt:10 Base address:0xf400 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:410 errors:0 dropped:0 overruns:0 frame:0 TX packets:410 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:20416 (19.9 Kb) TX bytes:20416 (19.9 Kb) route: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.0.0 * 255.255.255.0 U 0 0 0 eth0 192.168.0.0 * 255.255.255.0 U 0 0 0 eth1 loopback * 255.0.0.0 U 0 0 0 lo default 192.168.0.2 0.0.0.0 UG 0 0 0 eth0 __________________________________________________ Do you Yahoo!?
