Best practice solution for a blocked IP
I currently have several IPv4 aliases setup using block lists and a whitelist alias setup for IPs to allow outbound connections on my LAN network.
I have an issue with an IP address to access my webmail on an external network (my work) . Since my whitelist is only allowing outbound connections I cannot connect, and my WAN network does not have a whitelist rule. What is the best practice solution to allow me to access my webmail externally by passing the IPv4 alias IP address?
Your help would be much appreciated.
Just create a new Whitelist for the WAN. You can add the IPs to the customlist at the bottom. With pfBlockerNG-devel you can add IPs to the whitelist automatically by clicking on the "+" icon.
You can use the Adv. Inbound Rule settings, to only allow these specific whitelist IPs to access the mail server LAN IP and its open ports.
