Client beind NAT Firewall

Ok

I got a server at home, working well!

When I'm at my other home, on the network, I can't connect to the server, I got the "Please wait - Initial screen loading..."

I've tryed to use 56k to test and everything work fine.

The firewall is MASQ. and accept everything from internal to external, but only accept some port from external from internal. established and related connexion are accepted.

What (or where) should I look ?

sounds like the network is fine at all.
please try stable builds like RC18 instead of 19*.
what's different now?

I would check -

Port forwarding on router connected to your home with the server

and SP2 or any firewall settings on that computer or your viewer computer.

It could be either of the two problems.. or even something else of course

server @ home1 = working, tested with friend beind Linksys router and 56k at home2

client (laptop) @ home2 = working, with 56k
client (laptop) @ home2 = not working, on the home2 network, that is firewalled (go connected, but I just see a black screen)

no SP2, only SP1, tried on 2 computer (WinXP SP1) none working

I'm trying to be clear, but well... sorry

There is really only one answer to this - For some reason your router at Home2 is not properly handing off the connection. Take your router out of the loop (@home 2) and try to connect directly from the internet at Home2 this will eliminate your ISP.. which is doubtfull but still possible. You may have to reset your cable modem or DSL modem.. if your modem is the router.. that sucks..

After you do that it should work that way. Plug the router back in and dont ask me why but set up port forwarding on your router to go to your laptop at Home2. For some reason or another it sounds like that router is just not connecting your computers for some unknown reason.

I would also check for firmware updates on your router. BTW what kind of router is it? I would check out
http://portforward.com/routers.htm they have a lot of routers and even though you got one working right the other may have some stupid configuration to it.?

just my $0.02

I know it's a routeur problem, that what I'm trying to find!

I'm DSL ppp0 connected to a Red Hat Linux box (eth0) nat the internal network on eth1

and it's not the ISP

thanks for your help!
