Title: How do I redirect all outbound traffic to a port to an internal host
Post by: Taomyn on May 27, 2020, 11:22:32 am

What's the best way to redirect all outbound traffic, i.e. to the WAN, for a specific port to an internal host?


For example, I want any NTP traffic for UDP 123 not directed at my firewall to be diverted to the firewall - it therefore needs to allow the firewall itself to contact the external NTP servers it uses for itself.


I tried to use a manual Outbound NAT rule on WAN (Outbound NAT is set to hybrid), but nothing gets written WAN firewall rules so I have no idea where to check why it's not working. I'm running v20.1

I think you need to do it on LAN interface (where connection is incomming)

Thanks, it made no difference still no rules appear on the firewall

Did you add it by Firewall --> NAT ->port Forward ?

No by Outbound NAT because it's outbound connections I am trying to catch on the WAN interface
