I am trying to configure a RHEL 6 server as a gateway to the internet for an inner server.
The gateway server (server1) has 2 NICs:
default gateway 192.168.168.254
The inner server (server2) has:
default gateway 220.127.116.11
I have forwarding allowed:
# cat /proc/sys/net/ipv4/ip_forward
# iptables -L -n -v
Chain FORWARD (policy ACCEPT 79 packets, 6636 bytes)
I can ping and ssh from server1 to server2, and vice-a-versa. I cannot ping the ultimate gateway and beyond 192.168.168.254.
You can see from the FORWARD accept packets that the pings are arriving at server2.
I have tried to configure SNAT with this unsuccessfully:
iptables -t nat -A POSTROUTING -o em1 -j MASQUERADE
Thanks for any help you can provide.
