Really strange, it used to work and I could use the interal web proxy on port 3128 when connected via SSL-VPN (not "full gateway", only my LAN network is routed via tunnel).
Since a couple of months that is not working anymore. Tried checked different things like "Appliance access" giving VPN network access to Web Proxy which was enabled.
Strangely, I can telnet from my VPN connected PC into port 3128 on the gateway address of the Sophos Firewall and get a connection. Just web browsing using the Web Proxy is timing out.
