My ISP giving me two different IPs

Hi m8s,
I have setup my server and want to share externally.
I have installed the dns updater in my ubuntu server with no-ip.org and working fine
Command noip2 –S gives
No noip2 processes active.
Configuration data from /usr/local/etc/no-ip2.conf.
Account nobogy@gmail.com
configured for:
host plss.no-ip.org
Updating every 5 minutes via /dev/eth1 with NAT enabled.
I have also port forwarded the port 10000 in my router, command netstat -anltp | grep "LISTEN"
And I get
tcp 0 0 0.0.0.0:10000 0.0.0.0:* LISTEN 967/oscam
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 903/apache2
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 566/sshd
tcp 0 0 0.0.0.0:8888 0.0.0.0:* LISTEN 967/oscam
tcp 0 0 0.0.0.0:27000 0.0.0.0:* LISTEN 967/oscam
tcp 0 0 0.0.0.0:16000 0.0.0.0:* LISTEN 962/CCcam.x86_64
tcp 0 0 0.0.0.0:16001 0.0.0.0:* LISTEN 962/CCcam.x86_64
tcp6 0 0 :::22 :::* LISTEN 566/sshd
however I noticed that my IP in my router is different from my IP in

M8, 3G is not suited to this hobby.. i tried it out of curiosity myself & the service was up and down all day long... You cant make your external ISP IP Address static (There are some exceptions, Contact your ISP for more info) but you can make your internal machine static, I used re-routing software.. I had the wifi dongle connected to my desktop and that in turn was setup as a wifi/wired hotspot and allowed me to give it an internal Static IP Address... Im not sure about the software I used. I will have a look later on and update this post..

so what do you use mate?adsl....just advice
