OpenVPN via TCP port 443 is not accessible.
Hi, I configured an OpenVPN server on an old laptop at home using port TCP 443. They blocked many sites, so I expected normal encrypted traffic to work. However, the VPN failed on my school network despite working elsewhere and on my phone. I tried other ports like UDP 1194 and PPTP on port 1723, but nothing functioned. I have a web server accessible on port 80, confirming they aren’t blocking my domain. I found information about SSTP as a potential solution, but I’m unsure how to set it up on an older Linux machine. Any advice would be greatly appreciated.
The situation here offers very limited options. The high school I worked at relied on Sonicwall to block outbound connections to typical proxy and VPN ports on student networks. If your institution uses RDP internally, you might find some success by switching to RDP ports. Be aware of significant legal concerns regarding students accessing certain sites in educational settings, which is why these protections exist.
Most schools will implement a filtering service like Sonic, Smoothwall, or Lightspeed, which is likely preventing your traffic. It’s probable the school also monitors each client computer in real time and records all activity. Additionally, you shouldn’t be seeking ways to circumvent their internet filtering on this forum.
I faced the same issue. I solved it by installing the openvpn software and setting it up on my Wi-Fi and school networks. It functioned well for me.
