When i configure IP forwarding on Mobile Wan. It allways change back to NAT
Does your mobile provider provide you more then one ip?
yes. i have a fixed ip
You would only use ip forwarding if you have multiple ip blocks from your provider.
Example would be a /29 or /30 static ip on your wan and a /26 block on your lan side.
If you only have a single ip that use nat mode not ip forwarding.
the privider give me 1 ip and 1 gw. this is use for site-2-site vpn and it works on other wan ports.
Is that mobile port cant use to route all networks??
