Vigor2130 routing loop? was created by 1stewart
Hello,

We recently replaced an older DrayTek model with a Vigor2130 (last night in fact). Everything seemed to be working fine until today we noticed the odd stutter/timeout on pages. Checking the router we're getting an error 'received packet with own address as source address' in bursts every 30 seconds.

We've not changed anything other than swapping the router over. Our infrastructure is Zen Fibre -> Cisco Router -> DrayTek WAN -> Switches -> PCs and we also have a Buffalo WiFi for the odd wireless testing. Connectivity is solid, no clients are dropping and it's hard to notice the issues without investigation but there's definitely something wrong.

Unfortunately it's a production environment so until everyone leaves I'm limited to what I can check (badly terminated cables, bridged connections, IP conflicts), can anyone give me some advise what approach to take?

P.S. go gentle, I'm a junior fresh out of university :?
