Packet looping back

Hello



I am having a problem with a tinc VPN which is in switch mode.

Read packet of 121 bytes from Linux tun/tap device (tap mode)

Packet looping back to BVLAN996 (MYSELF)!



I just had one end of the VPN up and connected to another network and it
was running fine for a while and then it got the looping error.

When I have the other end of the VPN up also it is happily sending
packets, but when it receives traffic from the other end of the VPN it
just starts the "Packet looping" error and starts dropping packets.

It is running on CentOS 5.2 at both ends and is used to bridge another
network over our own network thru the VPN.



Does anyone have any ideas?  What extra information can I post to make
it easier to troubleshoot?



Thanks

Brent Ingram
