I'm configuring a new ASA 5505 for deployment as a VPN endpoint in a remote office. After configuring it and connecting the VPN, I get the following messages:
WARNING: Pool (10.6.89.200) overlap with existing pool. ERROR: IP address,mask <10.10.0.0,22.214.171.124> doesn't pair
10.6.89.200 is the address I configured for the ASA. It has the subnet mask 255.255.255.0.
The ip address 10.10.0.0 corresponds to one of our subnets, but it certainly wouldn't have a subnet mask of 126.96.36.199. That looks more like a public IP address (and resolves to an ADSL connection somewhere). I am sure if we had such a subnet configured, that it would indeed overlap with 10.6.89.200.
There is no reference to 188.8.131.52 in the config of this ASA or our head office ASA.
Can anyone shed light on what is going on here? The sudden appearance of a strange subnet mask is a bit alarming.
