I need some help, please. I have two LAN subnets with all my PCs on the 192.168.9.0/24 (Network a) subnet and some published services on the 192.168.254.0/24 (network b) network. Up until very recently, I was able to browse (port 443) to a server on network b from any PC on network a by its public IP address. This has stopped working. I can still browse to that server using its LAN IP and internet users can browse to it using the public IP, however, the browsing by public IP between the two networks has broken.
The hairpin NAT rule which I originally used to get this working is
IP Firewall NAT
add action=masqurade chain=src-nat disabled=no src-address=192.168.9.0/24 to-addresses=192.168.254.0/24
Perhaps a Firewall rule that I changed broke it?
Any help will be appreciated
