How to only allow source dyndns type host(s) to certain port
I want to restrict a port to only 4-5 friends who have there ip address change and all use dyndns type hosts . When I enter in the dyndns host url into the source I get
dyndnshost.domainhere is not a valid source IP address or alias
Is this just not possible is there a trick to this. I have searched diffrent terms I am not finding anything on this. maybe I missed something in the forums. can some one let me know or link or the trick
would really help with security locking things down. I am sure there has got to be othere folks who need or would like to do this
Hostnames are supported, but only inside aliases.
Firewall > Aliases, click +, give it a name, set the type to 'host', and then click + and add each of the dnsdns hosts you want at the bottom.
Then use that alias name in the firewall rule.
Hostnames in aliases are periodically re-resolved and updated when new records are found.
