IPFW DirectAdmin FIREWALL RULESETS AVAILABLE HERE

Hello Everyone,

Is it possible to block a port using ipfw in freebsd lets say I have a server with multiple IPs and I want to block one of my customer IPs port 25.

Any help would be appreciated,

Do you have any idea how to make it work fluent with EDNS0 (DNSSec)?

When IPFW is enabled with that configuration, I get the following error on dnsviz:

DNSKEY (alg 8, id 23746): No response was received from the server over UDP (tried 6 times) until the DO EDNS flag was cleared (however, this server appeared to respond legitimately to other queries with the DO EDNS flag set). (..., UDP_0_EDNS0_32768_4096)
and

No response was received until the UDP payload size was decreased, indicating that the server might be attempting to send a payload that exceeds the path maximum transmission unit (PMTU) size.
