I have read a few threads on this but have tested extensively and come up with interesting results...

I have a setup where I have an ADSL modem and a Linksys broadband router. When our LAN machines are set to use the broadband router as the default route to the net, the router (or skype?) is intelligent enough to route skype traffic via the LAN. File send for example, flies.

Having the same setup, but creating our own seperate adsl pppoe connections throws skype a curveball. The default route is then handled (I assume) by Windoze and all skypte traffic to each other is handled via the internet. File send is obviously alot slower for example.

Even more interesting to me is that I have route sentry running on mine - you know, to route local via my local only account and international via the international account... despite this, it uses the international route for the file send to the other LAN users. Ok, granted the other users are connected via international only... maybe this is the reason? Either way, it's wasting bandwidth and I thought Skype or routesentry could handle this.... Will investigate further to see how many relays when on pppoe...

Anyone know a way of (setting up routing tables perhaps?) in windoze or skype to guarantee local traffic is not sent over the internet?

UPDATE: Skype reports no relays on a call within the LAN, so there is no firewall holding us up, it is direct... any takers?

Skype checks the public IP first, if 2x computers do have same public IP, a scan gets done on private IP. Should the public IP's be different, Skype will definetely not even try to see if private IP's are reachable.
 
why are you using 2x pppoe connections? you can configure router to make these connections for you and split between local & international traffic. I'm using my MikroTik to do this for me - all my Skype traffic is routed internally
 
I have a Linksys WRT54GL. It would be fantastic if this router can do this (it can be flashed with open source firmware)... do you know if this can be done? I only know to do this using routesentry on the desktop, which results in different IPs.

Any tips on how to do it? ;)
