Outgoing SSTP connection can pass through any kind of NAT and firewalls – as long as TCP port 443 is allowed (which is normally the case). If the VPN client is behind a web proxy, then outgoing SSTP connection can go through in normal web proxy. SSTP does not support “authenticated” web proxies (i.e. proxies which require some form of authentication during HTTP CONNECT request).
