Re: Odd router setting blocking site access?

So, I've cracked it. I think!

Firstly the router page I said was called "Static Routing Table" is just actually called "Routing Tables" and appears to populate from the DHCP as in previous posts.

There is however another page below called "Static Route" which allows you to input your own routes. But how do you know what?

Well a bit of logic and trial and error, I tried this,

81.0.0.0 255.0.0.0 81.110.180.1

Now the routing table says,

Destination IP Subnet Mask Gateway Metric Interface
192.168.0.0 255.255.255.0 0.0.0.0 0 br0
81.0.0.0 255.0.0.0 81.110.180.1 0 eth2.2
81.0.0.0 255.0.0.0 0.0.0.0 0 eth2.2
0.0.0.0 0.0.0.0 81.110.180.1 1 eth2.2

Low and behold I can now access the site! I think I have now forced any 81.xx addresses to be routed to the Virgin gateway. Remove the static route and it fails again.

So, is this the right way to do it? What else may it break? Presumably it will only last as long as this lease holds and then a new gateway is set? And still, where does the original 81.xx route come from and why? Is this just a grade A kludge?

Your last post Kushan, got me thinking again to have another look.

Many thanks for all your inputs, happy to have any more clues as to why.

Every day is a school day, they say. This networking malarkey is easy isn't it? /runs and hides/
