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,
 
ipfw add <rule-#-here> deny tcp from <customer-ip> to me 25
 
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.
