A lot of ISPs configure their equipment to block VPN solutions. There are obvious reasons for doing so, which makes the VPN in nowadays meta state of the internet — an irreplaceable user resource.

A lot of users have issues with routers blocking their VPN service/routers blocking Ethernet VPN with varying reasons for this occurrence.

Ever wondered what router can block VPN? Just like you, other users wondered whether an Asus router can block VPNs, Netgear router blocking VPN, or CenturyLink router blocking VPN.

We made sure to offer some viable answers. Even though effective, these solutions are rather broad. For that reason, we recommend contacting either your VPN or ISP tech support, as they’re responsible for the execution of the application.

How to unblock VPN when blocked by the router (ISP)?

  1. Change the location, IP and get a proper VPN
  2. Change the protocol
  3. Check router settings

1. Change the location, IP and get a proper VPN

Before tackling protocol and router settings, the first solution we have to offer concerns location and IP. If for some reason, a certain IP address is blocked, you can switch to a similar geo-location and try connecting again.

Also, this is where the distinction between the premium and free-of-charge solutions gets clear. Namely, with premium solutions you will have no difficulties in changing IP addresses and switching to various server locations.

Install Private Internet Access

Private Internet Access

Our recommendation goes to PIA, a world-leading VPN solution with a massive network composed of 3292+ servers spread across 46 countries worldwide.

This impressive collection of gateways gives you more than enough room to choose and test server locations until you find the one that best suits your needs.

In addition, Private Internet Acces provides unlimited bandwidth especially useful for avoiding ISP throttling and it streamlines your connection via its fast, secure, and reliable gateways.

Bypassing restrictions is what PIA does best (while protecting your data with the highest level of encryption, of course), be it from your ISP, country or regional blockages, admin restrictions or regulation infringements.

2. Change the protocol

Lots of routers block standard VPN protocols, like Point-to-Point Tunneling (PPTP) or SSTP. There’s probably an option that allows you to allow these protocols to communicate freely, but it’s easier to manipulate settings within the VPN tool itself.

What you can do is switch between the available protocols until you find the one which will likely work.

Our best bet is to stick with the OpenVPN universal protocol which is the up-to-date protocol. In addition, it hardly gets any blockage by default from the ISPs, which is, in this case, the most important trait.

3. Check router settings

If you’re, on the other hand, limited to PPTP, you’ll have a hard time with certain internet providers. It operates on predetermined ports that can get locked.

And, in order to avoid this, you’ll need to either add an exception for the VPN, forward dedicated ports or disable the native Firewall.

We recommend googling your exact router for better insight on how to do that. Even though options are the same, the login access credentials vary.

Also, you can disable Windows-native Firewall or, even better and much more secure — add an exception for your VPN. That way it’ll communicate freely.


With that, we can conclude this article. In case you have a recommendation or question, feel free to post them in the comments section below.

They can and they do, similarly to national or governmental agencies, or public institutions like schools, hotels, and universities. The most common way through which ISPs block VPN usage is via port blocking and IP address blacklisting.
