I just want to verify an assumption. I see in the ACCESS section that the list of services has a LAN out checkbox which obviously allows outbound traffic on those ports. I am interested in the 'Public LAN Server' setting. My assumption is that if there is an IP specified, that means only that IP can take inbound traffic on that port. Correct? If so, does the 0.0.0.0 setting mean any IP can accept traffic provided there is a rule set?
I am specifically interested in this as I have two mail servers behind the same firewall and after setting up the new rules I had problems with the first mail server.
Thanks for any info and tips you can provide!
