Hi all
I got an RB450G and want to use it as firewall between the Internet and a mail server. I need to open specifically these ports and drop everything else:
Port 80 forwarded to mail server (for webmail)
SMTP
POP3
DNS
Can someone advise correct command? The below are all the relevant IP addresses (not actual for security purposes):
External: 77.21.20.2 /29
Gateway: 77.21.20.100
Internal: 192.168.0.10 /24
Mail server: 192.168.0.100 /24
Primary DNS: 70.20.1.20
Secondary DNS: 70.20.1.21
Thanks
