How can be used EBTABLES in addition to IPTABLES to forward traffic
from an internal LAN to an external?
Suppose that I have an internal LAN with private IPs, and a Gateway
that control the traffic to the outside, and I only need forward traffic
for certain MAC address regardless IP address.
INTERNET --> Gateway <--- LAN
I'm not sure if I have to enable the following modules in `sysctl.conf`:
net.bridge.bridge-nf-call-iptables = 0
net.bridge.bridge-nf-call-arptables = 0
I have tried with the following configuration, but nothing happens:
# ebtables -F
# ebtables -t nat -F
# ebtables -P INPUT ACCEPT
# ebtables -P OUTPUT ACCEPT
# ebtables -P FORWARD ACCEPT
# ebtables -A FORWARD -i eth0 -o eth1 -j ACCEPT
# ebtables -t nat -A POSTROUTING -s INTERNAL_LAN_CLIENT_MAC -o eth1 \
-j snat --to-source MAC_OF_EXTERNAL_GATEWAY_INTERFACE
Any thought will be highly appreciated.
I'm watching the answers carefully, since I have a somewhat similar problem. If
I find anything in my work which looks useful, I'll share.
