The issue is that I need to blacklist nonprod servers as forwarders are added on all nonprod servers to replicate prod environments and if I remove the blacklist apps will be deployed to all nonprod servers.
I was hoping for a quick solution to only allow nonprod08 while blacklisting the rest
If you have filterType=whitelist (the default) then all servers are blocked except those covered by a whiltelist entry. That's why I suggested whitelist=noprod08 to allow nonprod08 while blocking the rest.
You may be able to test this using the Preview feature in the Forwarder Management screen.
there are way to many servers that would need to be whitelisted (all windows servers etc). I currently whitelist all and blacklist nonprod* and a few others.
I am kind of looking for something like regex to blacklist 1-7 then 9-126 etc allowing 8 still to forward
Not sure if I can though
This would have been good information to include in the original question.
Consider changing filterType to blacklist so everything is allowed except those which are blacklisted.
If that still doesn't meet your needs then you'll need to get creative with the regexes used in the black or white lists.
