1.) Have IPSEC tunnel up. (Showing in VPN-> Monitor as up.)
2.) Have seven "remote" subnets, and three "local" IP addresses. For ease of explaining, let's call them 10.1/16, 10.2/16, 10.3/16, 10.4/16, 10.5/16, 192.168.5/24, and 192.168.6/24. And then the IPs would be 10.1.11.5, 10.0.1.5, and 10.0.1.6.
3.) Objects created for each single listing above. (ie, Remote1, Remote2, Remote3,...IP1, IP2, IP3.)
4.) Groups created for each "set". REMOTE_GROUP. IP_GROUP
5.) Bi-directional policies setup.
5a.) Source: REMOTE_GROUP Dest: IP_GROUP <Always, all, accept>
5b.) Source: IP_GROUP Dest: REMOTE_GROUP <Always, all, accept>
Now...here's the weird part. If they attempt pings from their site? Remote1, Remote3, Remote5, and Remote6 will work to ping IP1. Remote2, Remote4, and Remote7 will get a timeout error with the classic "The packet specifies its destination as..." Which is usually an ACL error in the Phase 2 setup, but we've both confirmed that the subnets match, and all looks good...
