STUMPED - can connect via LAN but not via Internet

Tue Apr 3 16:38:03 2007

Hey Chris!  Thanks!

I did locate that site early on, and I hadn't realized that I needed 5500. I
think I've since discovered that port 5500 is for 'host-initiated"
sessions...?  Not sure about that part, but I always launch from the viewer
side, and I've never forwarded 5500 before so I've never had an issue.

The part that I don't understand is how the Actiontec is going to know which
local IP I'm trying to get to. They list
Port Start
Port End
Port Map Start
...but I don't know exactly how to use those three boxes. Everything I've
seen says to place the same numbers in all three boxes, so that's what I've
done. The port forwarding is on a slightly different screen.

This is what I want. Assume internal IPs of 1.2.3.4  and 1.2.3.5 and
external IP of 10.20.30.40

Access from outside the LAN to inside
10.20.30.40:5901 ==>> 1.2.3.4:5901
10.20.30.40.5902 ==>> 1.2.3.5:5902

So I have a rule for 5901 and 5801 and 5501 and assigned those all to PC1
Then I have a rule for 5902 and 5802 and 5502 and assigned those all to PC2
Again, I've entered the same number in all three boxes.

I've created all these 'rules' in the Actiontec, and I've assigned them to
each pc as indicated. Like I said, I *know* I'm really close because I get
the password prompt, it accepts the password, and then I get the black
screen "Please wait...Initial Screen loading..."  

I just can't get PAST that point ..  AARRGggghhhhh!!!!!!   Somebody HELP
me!!!!!

Hi Bruce,

After receiving good advice from this list that told me that my problems
were related to port forwarding I followed the directions on this site:

http://portforward.com/english/routers/port_forwarding/Actiontec/GT704-WGv2/
VNC.htm

This site should answer your questions about ports 5500, 5800, 5900, tcp and
udp.

Hope this is of use.

Chris

Hello Chris, et al

RE:  http://www.mail-archive.com/vnc-list@realvnc.com/msg24978.html

I have the same problem Chris listed here, but I think I need a few more
specifics. What ports are needed to forward? I had this working fine on my
old router with cable internet, but this Actiontec is not very user
friendly. Anyway, do we have to forward 5500, 5800, and 5900? And did you
have to set it for tcp AND udp?

My setup is that I have two pc's that I need to access. (false IP's listed
here for reference)

Static IP from ISP   175.152.15.67   

Internal Static IP's   100.25.15.61 & 100.25.15.62

Old Setup with Netgear Wireless Router

Port Forward: 5911  to  100.25.15.61:5911

   PC1 VNC Server set to (*) Ports Main: 5911

Port Forward: 5912  to  100.25.15.62:5912

   PC2 VNC Server set to (*) Ports Main: 5912

So VNC Viewer access from the WAN was simply 175.152.15.67:5911  or
175.152.15.67:5912

Worked great.

New Router: Actiontec GT704-WGv2

Current problem: VNC internally works fine. Right now, accessing from the
WAN, I can get a password prompt from VNC, it accepts my password, then the
screen goes black as it's 'loading' but never completes. It eventually times
out and disconnects. So I know I am close but don't have *everything* quite
right.

PC 1 - Static internal IP 100.25.15.61

   VNC Server set to (*) Ports Main: 5911  Http: 5811

PC 2 - Static internal IP 100.25.15.62

   VNC Server set to (*) Ports Main: 5912  Http: 5812

On the Actiontec, I have upgraded the firmware to 3.20.3.3.5.0.9.1.5

Under Security - Applications I have applied the following rules

PC1: 100.25.15.61

TCP  Port Start: 5911  Port End: 5911  Port Map Start: 5911

TCP  Port Start: 5811  Port End: 5811  Port Map Start: 5811

PC2: 100.25.15.62

TCP  Port Start: 5912  Port End: 5912  Port Map Start: 5912

TCP  Port Start: 5812  Port End: 5812  Port Map Start: 5812

I get the same result from each pc when I try to access from the WAN. I get
the password prompt, it accepts the password, then goes black as it tries to
load the desktop. Eventually it times out and disconnects. I know I'm
close...!
