TL-WN727N as WAN interface

[NightlyShark]

@bavcon22 I am sure something will turn up (speaking from personal experience from my net MacGyver years). If you need anything PM me.

@bavcon22 said in TL-WN727N as WAN interface:

The M7350 does not offer port forwarding over USB connection.

Does it offer port forwarding at all? I don't imagine it uses a different subnet for the virtual Ethernet port. If it has any sort of forwarding capability I would expect to be able to use it with a USB connected client device.

@stephenw10 The device tp-link M7350 has NAT forwarding section and subsections with name:

• Application Layer Gateway (ALG)

• Virtual Servers

• Port Triggering

• DMZ

• UPnP

Picture from Virtual Servers:

Telnet is only for representation, I do not use it. I only use this for VPN.

@bavcon22 Virtual servers is port forwarding with NAT (ie, in pure port forwarding ports are the same internal, same external. Here they can be different internal, different external).

[stephenw10]

Yes that. And the DMZ section would almost certainly allow you to pass all traffic to pfSense which is probably what you want here.

[bavcon22]

@stephenw10 My public ip is
at the same time the modem IP is

My question: Is there another NAT or what?
If I'm conected with my phone directly to M7350 LAN with pfSense the VPN works, but in mobile networks does not work at all.

On M7350 I tried the DMZ with no luck and forward the port also with no luck.
I think the ISP has another NAT that I can't access it.

[stephenw10]

Yes, there could be be CG-NAT at the cell provider. Probably nothing you can do about that unless they offer you a static IP at additional cost.

@stephenw10 Just a note, at least in my country (Greece), bitching to ISP tech support can surprise you. I got them to not just remove my account from CG-NAT, but to also remove the MAC ACL for my account AND provide a (CG-NATed) IPv4/32 for the CPE (telephony). I still don't know how to get them to provide a guaranteed static IPv6 prefix...

[stephenw10]

Nice. Never hurts to ask I guess.

@nightlyshark Thank you for jour help.
