I'm currently trying to make a squid server on my personal laptop to allow a few PC's on my work to connect to the internet through a vpn on my laptop.
I've installed and configured squid on my laptop running Debian 9, and connected my laptop to my work LAN (IP = 10.75.245.21).
Then I've configured a PC running Windows 10 (IP = 10.75.245.20) to use the proxy on my computer (port = 3128). But when I try to access any internet page the conexion fails.
any ideas on how to fix it?
Adicional information
All computers in the LAN have fixed IP with the subnet mask 255.255.254.0 The network here also have internet access but has a very strict firewall (the motive I want to route connections through VPN) All computers and my laptop are in the same subnet My computer is also connected to a wireless network. I am using a cisco protocol VPN on my computer
when I try to open an internet page the command netstat -na | grep 3128 on my computer (server) shows:
tcp6 0 0 :::3128 :::* LISTEN
tcp6 0 0 10.75.245.21:3128 10.75.245.20:52802 SYN_RECV

tcp6 0 0 10.75.245.21:3128 10.75.245.20:52799 SYN_RECV
and the netstat command in the client shows:
