I have a FWG. Is it possible for me to let one or two IP addresses access my Raspberry Pi using the rules or PBR feature? Currently, I forwarding a few ports (ssh [52222 --> 22], ftp [52221 --> 21]) to the RasPi. However, I'd like to only allow only a few IPs or IP Ranges to access this RasPi. How would I set up an "Allow From Internet - IP: 220.127.116.11, 18.104.22.168. Deny from Internet: All Else"?
I asked 'support', and they said:
should have the feature you are asking.
You can block all traffic to your pi first, then use above feature to allow
-- However, I couldn't quite figure out what they were telling me to do. Follow-ups with support were just as unhelpful.
I THINK I can make it so a particular IP can access, but - How does that also use the Port Forwarding feature?
