NAT Internal Access

Azazel 0

Hi All,

I am new to pfSense, so I am getting myself confused.

I have created NAT rules to connect to my Synology NAS for the DS Camera app.

That is working fine externally, but if I'm on the internal network, it doesn't work.

I have had no-ip setup for DDNS for a long time now, and this was working perfectly when I was using a unifi USG.

I'm just not sure what I'm doing wrong or missing.

If you are using an internal DNS like the Resolver on pfSense, add a host override for your public host name.

nslookup shows it resolving to the internal IP

But when I try my port forwarding internally, it doesn't respond

Here are some screenshots which might help

321 is just an example for the external source port

You're possibly meaning the destination port.

Do you a port translation in the NAT rule to access this server from outside?
Consider that a host overrides does no port translation and you cannot do it on pfSense without SNAT if both, client and server are within the same network segment.

Also consider that you have to add proper firewall rules for allowing the traffic in the case that the access has to pass pfSense.

I did some further testing and found that it was pfBlockerNG which was causing the issue.

I'll have a look at my settings in it later today.

Thanks for your help
