Hello to all.
I get into troubles.
I need to put my "ready to" run server into a private local network in a school, for mail, http... etc.
I asked the Internet Service Provider to forward the needed ports:
22,25,53,80,110,143,465,993,995 to this server.
The server is on the LAN 10.4.46.x with IP adress 10.4.46.2.
I requested the ISP to forward this ports from public static IP 184.108.40.206 to my Local. (server)
They answered something what I don't really understand.
These forwards are active right now on the ISPs cisco router:
ip nat translation tcp-timeout 600
ip nat pool Dynamic 220.127.116.11 18.104.22.168 netmask 255.255.255.248
ip nat pool NATPOOL 22.214.171.124 126.96.36.199 netmask 255.255.255.248
ip nat inside source list 105 pool Dynamic overload
ip nat inside source list NAT pool NATPOOL overload
ip nat inside source static 10.4.46.10 188.8.131.52 extendable
ip route 0.0.0.0 0.0.0.0 Dialer0
They asked me if I want to remove all of this and make a port redirection from the Public IP to my private IP (server).
I believe that there is some range of Public IPs which can be used. But I didn't really understand this printout.
I know it is difficult to help without knowing the exact network structure but any suggestion may help.
Thank you very much!
