It's already been discussed here and a solution presented by pbix - the only downside is that upon a FW upgrade you have to manually implement this each time. Not a big deal, just thought it might make things easier

Code: Select all
MODEM_IP="10.x.x.1"
VLAN_IP="10.x.x.2"
ifconfig eth0.1 $VLAN_IP netmask 255.255.255.0
iptables -A forwarding_rule -d $MODEM_IP -j ACCEPT
iptables -t nat -A POSTROUTING -d $MODEM_IP -j MASQUERADE
