No Internet connectivity

HI all

 

I've been given a range of 5 IP addresses from BT one of which I've assigned to my server but I can't get out to the internet on the server

 

Setting for my server:

 

IP = 81.138.148.yyy

subnet = 255.255.255.248

Gateway = 81.138.148.xxx

 

Hub/Router address = 81.138.148.xxx

 

Have I missed something on the server ?  I've got DNS Setup on the inside and can get name resolution OK but I think somehow somewhere the hub address/gateway address is wrong?

 

Thanks

 

Lee

What router are you using?

The BT 2700HGV-C 2Wire ..

There's a few things you can try.

 

You need to ensure the public network has been enabled on the router via Settings> Broadband> Link Configuration and scroll down to Public IP Address... enter your gateway and subnet for your IP's here.

 

If you've just ordered the static IP's, you need to reboot your router.  If your router is still on the same session it had before you purchased the IP's, then a reboot will let the IP's map to your login.

 

Ensure you're connected on the correct username and password, all IP mapping is done via the login process, if you're on the incorrect details the IP's won't route properly.

 

If all of the above has been done and is correct and you're still not getting web, assign the IP to your server and do a tracert to google's IP (209.85.137.94), if you're getting about 4 hops in then timing out, it's possible another router is connected on your login details. Do you have more than one BT BB line in the premises? Do you have a line in another location but the router for this site was sent to that location?

 

if you're still not getting web with your statics after all that, the best option would be to call the helpdesk.

We have internet connectivity from inside the private network - 192.168.1.0/255 and that's working fine.  I't simple the machine that I have assigned a static IP address to.

 

The checks below have all been done - The router has been given the IP address and correct subnet - whats the "Auto Forewall open" option?

 

When I do a traceroute  to google I can't get past the first hop - which is the Router IP address so it looks like there's no traffic going past there.

 

Strange thing is, is that I can get to the machine from the outside world!  I've got a web page open on there and I can hit it no problem - it's just outbound traffic from the server

Do you get the same symptoms if you assign another IP in your range to a standalone PC or laptop?

Hi

 

Yes any address within the range we've been given fails.

 

The range is 81.138.148.177/248

The router/hub is 81.138.148.182

 

but everything stops outgoing at the Router

In that case I would give the helpdesk a call.

 

Sorry I forgot to answer your other question, auto firewall open means that the firewall will automatically be lowered to any device that's configured with 1 of your public IP's.

There's nothing on the firewall to block outgoing traffic by default ?

No there's nothing that blocks it by default, and if you can get web via a private 192 IP over the routers dynamic peer address then no custom settings have been applied in the firewall advanced settings section as all traffic would be blocked, not just traffic used by the public IP's.
