To set up ASE to separate PK++ servers from VPK servers, do the following:
1. Open ASE
3. Add in the filter string
'1 if modname ~!= "*PK++*" remove'
4. Open the filter on the right-hand panel, now showing PK++ servers.
If you want to be more advanced you can separate them by PK++ version number also, since PK++ gives the version in modname, such as: PK++ 22.214.171.124
