Help with NAT

[dmconde]

Hello,

I am having problems with NAT, i have tried to NAT port 5900 to a computer (to connect trough internet, I know PPOE and IPSEC but I want to do this) and no way, I don´t know why.
I´m going to explaind my config:

ADSL(Router ZYxel)  Nated all ports to Pfsense IP –->Pfsense (NATed port 5900 to a computer)---->LAN (computer)

In Port Forward -----> WAN  --- TCP/UDP --- 5900 ----  192.168.0.100  ---(ext.: 192.168.1.34) --- 5900  ---- VNC computer

It´s possible the problem was because of natting the ports from DSL router to PFsense and from Pfsense to the computer?

Thanks in advance
David

As your WAN is a private IP-Adressrange make sure "block private IPs at WAN" at interfaces>WAN is unchecked (it's enabled by default). In case your firwallrule was autocreated when adding the NAT i doubt that the problem is at the pfSense end. You might want to add a "log" for the rule that covers this NAT. You should see a pass event at system>systemlogs, firewall logs when trying to establish the connection. If that doesn'T happen it most probably gets stuck in the router in front of the pfSense.
