[vox-tech] Linux as gateway



-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

hi,

I'm trying to let a Redhat 7.1 act as a gateway, following steps are
what I did on the gateway machine:
1. echo 1 > /proc/sys/net/ipv4/ip_forward
2. ensure iptables's all default policies to be ACCEPT, such as FORWARD,
INPUT, OUTPUT, POSTROUTING...

Then in the internal machines, I set the default gateway to be the
internal ip address of the gateway.

>From the internal machines, I can ping the internal ip address of the
gateway, and the external ip address of the gateway. But when I tried
to ping some other external ip address, it always failed without any
response.

Anybody can figure out if I did something wrong? Thanks a lot!

Jimmy
