Access internal computers using external IP & ports?

How do I set this up?

From external computer:
<dyndns.org-domain>:3000 -> goes to pc1:3389
<external-ip>:3000 -> goes to pc1:3389

That works fine.

But if I'm inside the network:
<dyndns.orgdomain>:3000 -> times out
<external-ip>:3000 -> times out
pc1:3389 -> goes to pc1:3389

How do I make pfsense loop back like that inside the network?</external-ip></dyndns.orgdomain></external-ip></dyndns.org-domain>

I would like to know that too.
I know that juniper has this default in there config.

I do it using a dns. I just change the ip from what x.mydomain.com resolves to.

Example test.domain.com –> XXX.XXX.XXX.XXX
In my local dns it resolves to 192.168.1.1

Can you explain how you set that up? Did you use the DNS Forwarder?

You can create local dns entrys in your own dns server

But its the IP that doesn't seem to loop back.

Accessing 24.34.44.54:8080 just times out inside the LAN. Accessed from the WAN it forwards to the proper pc.

For example:
custom.dyndns.org -> 24.34.44.54
pfsense -> 192.168.1.1

So I go into my local DNS server and manually set:
custom.dyndns.org -> 192.168.1.1

pfsense forwards port 8080 to 192.168.1.20

and I try to access custom.dyndns.org:8080 is going to point to pfsense:8080 not 192.168.1.20:8080

does this mean I have to set my custom dns records for each pc?

outside:
custom1.dyndns.org -> 24.34.44.54
custom2.dyndns.org -> 24.34.44.54
custom3.dyndns.org -> 24.34.44.54

inside:
custom1.dyndns.org -> 192.168.1.20
custom2.dyndns.org -> 192.168.1.21
custom3.dyndns.org -> 192.168.1.22

?

That seems like a really bad way of doing it…

Only the machines you have to access via wan address.

The problem you're facing is called NAT Reflection and if you search the forum you'll find more about how to deal with it.

Wow, just one check box, thanks :)

That's exactly what I wanted to do.
