I want to connect two GL Inet routers through a tunnel VPN. I am unable to establish the connection and please advise which port number ( TCP / UDP ) that i need to use for the port forwarding on my ISP modem and which port number that i need to assign.
First, what type of VPN are you setting up (PPTP, OpenVPN, IpSec, etc)? Each uses different port numbers. Are you running VPN on a computer or on the router?
My GL Inet router supports OpenVPN, Wireguard, and Tor out of the box. Luci allows PPTP and others, I believe. So, which one are you going to use? Open VPN uses 1194 (and often 443 for fallback) by default, PPTP uses 1723 and needs for the router to have gre47 (which most have). In both cases I’d just select TCP/UDP when it asks what protocol for the port - even though TCP alone usually works. UDP is faster, but sometimes doesn’t work due to a variety of reasons. I can’t speak to Wireguard.
my main ISP router from the living room is an ATNT Uverse that is connected to my centurylink router that goes to my bedroom and from there i have a little netgear switch that is connected to my centurylink router and provide internet to all my room devices through lan port including my GL Inet which i configure as a server. i download the server configuration then export it to my other router from another country where i have another GL Inet client which the connection refused to established.
please kindly help me with a few ideas that might be missing on the configuration
my GL router is not connected to my main router instead its connected directly to my a little netgear switch which is connected directly to my centrurylink router and my centrury link router is the one connected to my AT&T Uverse router. Do you thin i still need to configure port forwarding from my main router to the GL router even though its not directly connected to it ? or should i configure two port fowarding one in my main router to the centrurylink and the other from my century to the GL router ?
my atnt main router refused to accept the port forwarding.
It does not have the option to port forward the ip of the remote router instead gave me option to port forward a specific port number or open the traffic for all ports. I selected either option still the port forwarding does not work. i think this is where the issue come from
