server behind a modem router

[isaia]

i have ADSL 2 + connection
and i use a Modem Router hardware witch is Billion 7402 VGP...

the modem gets te real ip.. 220.233.185.147

and my local network is 220.233.135.*

before i had 8 Ips ftom my provider... but now i have just one and a internal network...



it is imposible to put on eth0 the real ip,all i can put is only a local ip cause the real ip ta has been taken by the modem...

soo how can i make DSM work on my internal server... keeping in mind that eth0 has a local ip witch is difrent then the real ip...

real ip on modem : 220.233.185.147

local ip on server eth0 : 220.233.135.100
i can not put real ip on eth0... i need DSM to work on the internal ip....


can be done ? and if yes please provide an example... thank you

Your LOCAL network really shouldn't be using public IP addresses.
and my local network is 220.233.135.*

it should be something like 192.168.1.* or 10.0.0.* or some PRIVATE non public IP address 220.233.135.* is using public IPs behind a nat router and that is not good practice unless you have been assigned that IP range to use by your ISP. If so forget all I have said.

If you haven't been specifically assigned those address chanage you internal network to set to the private IP ranges. Then set the router to forward the needed ports to your webserver 21,25,53,80,443, etc.
