Can I use appear.in behind a Firewall or Proxy Server?

Firewalls

We do understand that many organizations prefer to route their network traffic through a firewall to improve privacy and security. However, because appear.in is a peer to peer service, we do need some traffic to be allowed through the firewall. We require that outgoing traffic via TCP and UDP on port 443 is open, so this change will need to be made by your network administrator.

Proxy or VPN Servers

At the moment we don't use a static range of IP addresses for appear.in's servers, so we don't recommend using appear.in behind a proxy or VPN. In some cases users will have initial success using appear.in behind these services, but in many cases those users do end up experiencing connection issues at some point in time.
