Since I've set up the routed IP's on my router (Linksys WAG54G) all was seemingly well. All websites work and each pc can be accessed by it's own static IP. BUT I cannot access hotmail or yahoo (so I assume it's an authentication problem). I've been googling and trying various things to no avail, one of the main googles returns info. on how to change MTU settings, but this has no effect.

Anyone got any ideas?

PS> It's def the router as all 4 pc's cannot access hotmail/yahoo_mail.
