7800N NAT Question
Posted: Mon Feb 13, 2012 9:58 pm
I recently purchased 3 Billion 7800N's after much research on the internet trying to find the best ADSL routers available.
We have 3 locations, at each loaction buildings are very spread out so we we have multiple wireless links linking the various places we need LAN at back to the main office at each site. Anyway in order to keep the traffic across the wireless links ot the minimum we have each wireless link on a seperate subnet. The issue I have with the Billion 7800N is that is seems to only perform NAT on the local SUBNET as per the LAN IP address set on the unit itself.
For example I have a 7800N on 10.10.0.254, it will perfoem NAT fine for all PC's on 10.10.0.x however traffic from any of the wireless links EG: 10.10.1.x, 10.10.2.x etc is not getting natted. All routing is fine I can ping the 7800N (10.10.0.254) from anywhere. I have a temporary fix where I am NATTING all the incoming wirless traffic on the wireless units at the 10.10.0.x end. However I do not want to double NAT. Is there any way of getting th 7800N to NAT everything that is destined for the WAN/ADSL port irrespective of IP ?
