Citect is running fine on the local network, but then crashes when I connect to a WAN. Over the WAN there are multiple projects also running.

Please check that the IO device numbers are unique across the different projects. They may be separate projects, but the servers use the IO device number to find a device, which may cause a conflict.

Having the same numbers across servers which are connected appears to cause them to crash or hang.
