port blocked universal media server xfinity

I can appreciate doing this for a variety of other reasons, but for some of us, the latest Xfinity modem is actually the best on the market for our needs and it kind of gets a bad rap due to their long history of crappy modems or other misinformation. I ended up finally getting my own modem/ router which was probably long overdue. If you turn off forwarded ports, and then turn on Advanced Security, you can forward the ports again without this issue. I think this is a bug, but if you have ports forwarded before turning on Advanced Security, it will always warn you about those ports, even if you allow access. Step 2) Find the appropriate networking section. If you click through on the threats, you can then allow access: You can go through the security page and see what threats it blocked. It really should be viewed as beta, since it just launched and has a lot of learning to do before it's ready for everyone.

I've done some research, and found that Verizon only blocks port 25.Xfinity Advanced Security is optional. My friends that have Verizon are able to stream with no problem at all with bitrates as high as 8,000. To my surprise, the scan found one open port: Discovered open Advertisement Coins. Even if someone ran an open mail relay on port 25 on their machine it could not send any mail out because of the port 25 would be blocked going out of the modem. I'm honestly starting to think this boils down to the fact that Xfinity blocks numerous ports: Out of curiosity, I ran a port scan on the public IP address of my Xfinity cable modem. I posted on r/mixer, and it looks like other Comcast users are having the same exact issue: I've contacted Xfinity support and Mixer support numerous times, but neither can really figure out what's going on. aaaaaand I still have the same exact issues.

I figured it might have been because I only had 10 mbps upload while on the Blast internet package. This problem has persisted since I started streaming. When trying to stream at anything above 1800 bitrate, my stream starts to lag, frames are dropped, and I get disconnected. We recommend learning more about configuring your email settings to Comcast email to use port 587. This does not affect Xfinity Connect usage.

IPv4/IPv6: 25: TCP: SMTP: Both: Port 25 is unsecured, and Botnet spammers can use it to send spam. This protocol uses UDP packets to transmit information, while Twitch uses RTMP protocol, which makes use of TCP packets. Network abuse has prompted the need to block this port. I'm a streamer on Mixer and I've been having troubles streaming at a high bitrate while using Mixer's new protocol called FTL.
