I have one site that should make two VPN connections through a 2600 Plus:

Let's call the remote sites A and B!

The router makes a connection to A and B OK, but also makes a third connection using A's LAN address but it connects this to site B. so I get:

Connection to site A A's Public IP A's LAN IP 192.168.126.0
Connection to site B B's public IP B's LAN IP 192.168.130.0
Connection to site B B's public IP A's LAN IP 192.168.126.0

At face, value, this seems to be some kind of misguided spanning-tree routing (have to admit I've not done a traceroute yet) but I haven't asked for it and I have checked all the visible settings and RIP is turned off at all sites. Is there something through the telnet interface that may need turning off??

If I kill the unwanted connection, routing to/from site A stops, which implies that all their data to/from site A is passing through B - also borne out by the staff on site complaining that the connection is slow.

I have an identical site that is also making connections to sites A and B and this one's working fine. Comparing setups I cannot see any differences at all, right down to firmware version.

Any ideas?

Thanks
