softether servers will only connect over udp protocl

Post by ezekial52787 » Tue Oct 24, 2017 6:13 am

they refuse to connect over TCP protocol. What do you think is the problem? I am using trendmicro maximum security, adguard adblock for windows, and malwarebytes anti-exploit, and just windows firewall, so what could be blocking the TCP connections? if you know, then could you explain to me step by step, what I should do. I just now finally got this set up, and it's kinda annoying that it's all slow as crap because I have to use UDP protocol. Also, could someone explain to me how to add the OpenSSL servers to the list as well.

Why do you think TCP is faster than UDP when the reverse is actually true, see this (and many other reference on the internet): https://stackoverflow.com/questions/479 ... ster-is-it

because's the connection is so much slower now, even if I use a a server relatively close to where I actually am, and even if the ping is very low according to the server. Also despite the connections Mbps being very very high.

I guess it does not matter, but I just need to know one thing, is using the udp protocol less secure than using the TCP protocol? because the TCP protocol says it uses HTTPS.

I want to correct your misunderstanding.
In SoftEther VPN, NAT-T mode (in UDP) is wrapping whole HTTPS protocol.
Security strength is equal for TCP and UDP.

For performance, depending on the situation, either TCP or UDP may be advantageous.
UDP is advantageous in poor environments with many packet loss, large delay and narrow bandwidth.
TCP is advantageous in environments with few errors, low latency and wide bandwidth.

That might explain why softether is only allowing connections via UDP protocol, as we have many people all using our wifi on a measly 6-12 Mbps DSL connection. That, and I had to install a wifi extender just so one half of the house could actually receive a decent connection. It's a dual-band extender, but still. Our router is also a dual-band router, but that only helps so much, when it comes to bandwidth. Thank you very much for clearing that up, Cedar Sir.
