And, following is the output from ipfstat showing the relevant rule(s).
@140 block in quick proto tcp from 82.0.0.0/8 to any port = smtp
If I am looking at everything correctly all traffic coming into the
system from the 82.0.0.0/8 network to port 25 on the mail server
should be blocked.
What am I missing?
I can't tell you what you're missing, but we're missing the entire
story. Just because you have a block rule doesn't mean that things will
get blocked if you have a pass rule before. You need to post the entire
ruleset if you want help with that.
Evidently, things get passed by some other rule, you can get a clue by
adding the log action to all rules passing packets to port 25 or any port.
When adding new rules it is a good idea to add log statements so you can
debug. Once things work, remove them to reduce the noise.
