Firewall blocking too many SSH connection attemps

Product Support
#1

Our corporate firewall is blocking the UnderPass tunnel client because it attempts too many SSH connections within 60 seconds (20 attempts). Is there a way to configure this somewhere in the UnderPass app or elsewhere?

Hi @robert.carr

Please try to whitelist UDP and TCP traffic on the stun servers shared below and also open 80 and 443 ports for these IPs… Although stun servers are hosted on 443/80, Webrtc by design communicates over a range of ports(1000-65535) on UDP or TCP for Peer Connections.

Please see DNS names of stun/turn servers to be whitelisted:

stun-us-2.lambdatest.com:443

stun-ap-2.lambdatest.com:443

stun-eu-2.lambdatest.com:443

stun-us-1.lambdatest.com:80

stun-as-1.lambdatest.com:80

stun-eu-1.lambdatest.com:80
