LAN to LAN via IPSEC , Not all hostst are working?



  • We have a PfSense instance running on a hosted server, 4 different locations are connecting to this PfSense instance using Draytek 2860 endpoints. All locations are connecting without issue. All Draytek devices are running the same FW version. All VPN Tunnels are configured the same across both devices (PfSense, Draytek endpoints)

    1 Site however, is having a strange issue. If I run an IP Scan on the local network - I detect 45 hosts. If I do an IP Scan from the cloud server, I only detect ~25 devices. The devices that simply aren't being detected, aren't in a specific IP Chunk or even in the same physical location at the site - I cannot establish any sort of pattern between what is detected and what is not.

    A good example would be 2 printers, connected to the same switch, that runs directly back to the Draytek on the site.

    I've checked the network config of both printers, they are both OK.

    Any idea's because at this point - I'm stumped!



  • Are the subnet masks configured correctly on the target PCs? I just ran into this after changing our entire network subnet - some of the devices I had not yet rebooted were still on the old subnet.
