Hey all

All the views and suggestions are welcome.

Current Structure
1. XP PRO SP2
2. ADSL ROUTER [BEETEL 220BX]
3. NETGEAR WGR614v5
4. STATIC IP [no-ip.com]
5. Dynamic IP to Static Ip app [no-ip.com]

ADSL ROUTER
WAN IP/External IP: no-ip.com
LAN IP/Internal IP: 192.168.1.x

NETGEAR ROUTER
WAN IP/External IP: 192.168.1.x
LAN IP/Internal IP: 71.168.1.x

Current Port Forwarding
From ADSL ROUTER I forwarded port 5900 to 192.168.1.5 viz. my NETGEAR router's external IP. From netgear I forwarded the same port to Internal IP.

Situation
I want to use RealVNC or something similar from office. Also, at times I need to help my family members and frens with certain computer stuff, so I would like to control their machine at times.
For accessing their pc I prefer using ULTRAVNC or similar.

Problem
I can not use any application. Though when I checked the port setting with http://www.realvnc.com/cgi-bin/nettest.cgi it says failed for the first time but second time onwards it says SUCCEEDED. Though with http://canyouseeme.org/ it says blocked.

All the help is much appreciated.

For double port forwarding I used the concept from:
