16.7.3 port forwarding

[stewconsult]

Just install 16.7.3 on new box...  setup lan and wan interfaces, nest thing I did was setup NAT, port forwarding

I tried using wan DHCP    as well as static WAN  IP    but nothing is working.

I have upstream gateway which is a frontier DSL modem , made subnet /24   on static WAN

I am trying to forward port 8100 which is a management port for an app I use.   I forward frontier modem to wan interface of opnsense, then forward wan to my lan ip, it creates a firewall rule appropriately.

I'm using canyouseeme.org to check for port 8100.... no good.

My normal router works fine  (Mikrotik)

Any ideas?

Try Firewall: Settings: Advanced: check "Disable reply-to on WAN rules".

Thanks. Just reviewed a pfsense doc, it says to use
WAN ADDRESS    as destination  in port forward rule. I thought the opnsense docs said to use LAN ADDRESS

Its working now for me.

Which OPNsense doc are you referring to? If it's wrong, we should certainly fix it.

Franco these option not is for MultiWAN scenario ?

In the NAT option wizar on port forwar you change the NIC destination for LAN address ?

I can not fixit yet, how fix it ?

Yes, you are right. If you use Multi-WAN you should try to disable reply-to via the per-rule option in the rules edit screen.

I don't see any documentation on setting up a simple port forward in the manual, musty have read in somewhere on google.

So the thing is that we do not know how do a simple port forward, using our knowledge on others firewall platform.

That desire to do the difficult things about OPNsense.

There is an interesting thing about port forward.

Before check this, the outer port can only be accessed from Ubuntu 16.04.01.
The outer port cannot be accessed from macOS, the TCP ACK packet is sent from WAN interface, but macOS does not receive the TCP ACK packet.

After check this, the outer port can be accessed from all kind of OS.

Try Firewall: Settings: Advanced: check "Disable reply-to on WAN rules".
