Cannot view pages on lan server via wan i.p.


Hi All,
I have an web server behind a DSL Modem with a fixed I.P.
I can get Http from a lan ip with a lan pc. I Can get Http from wan ip from any other site.

I basically want to be able to "see" my wan http adresses like others do , i.e. open my wan page from behind the same modem.

My site is both hosted by a company and it calls for my local (home) server as part of the application... works fine.

My problem is that i need to be able to test the prog at home and get page cannot be displayed when using a wan ip from a lan p.c. (only parts of the prog have wan address (of my home) and i don't want to have to edit these out each time i test)

When i had a cable modem , this worked.
Now I get the modem admin page (although the modem's wan remote admin is disabled, but i assume that this is because i'm a valid lan manager of the modem
If i disable managment alltogether, page cannot be displayed


this is tracert from lan to wanip

Tracing route to 60-240-XXX-XXX.tpgi.com.au [60.240.XXX.XXX]

over a maximum of 30 hops:


1 <1 ms <1 ms <1 ms 60-240-XXX-XXX.tpgi.com.au [60.240.XXX.XXX]


Trace complete.

thanks david

It sound to me like the NAT in your modem is blocking access. If that is the case, you will likely need to use a shell account on a machine outside your LAN to access your website.

HTH,
Ross.

rosscoad is right it is a nat issue or more a firewall issue. We had this problem at work and it turned out that the firewall(like any good firewall shouldn't) wont allow inside traffic to loop back to keep you from having a problem with people spoofing internal ip address to bypass the firewall.

makes sense Romsieze,
Shame you cant allow this on port 80 though,
A remote pc for the purpose of testing is a bit of a drag

thanks anyhow Guys

The way I've always done this is to use a web based proxy from my lan machines and entered the public ip of my server. So basically you're going "out and in" again.

Something like this will do it.
