Egress filtering not working
Guest last edited by
I followed the Egress Filtering guide - now I can't connect to the internet.
As soon as I enable IPv4 allow all - it works again.
You miss the rule allowing DNS….. (TCP/UDP :53)

Also you might want to consider not to allow port 25 and instead allow 465(SMTPS), 587(MSA, submission).
Also 993 for IMAP.
To make this more manageable you should start using aliases.
You don't want to have many many rules when you can do everything with a single rule and an alias.
