Hello All,

I am currently researching a solution for tunnelling VoIP traffic since VoIP is blocked in the country concerned.  It appears that the ISP is targeting OpenVPN and OpenSwan and blocking them so I want to try something different.

My solution based on OpenVPN worked great until it got blocked by the ISP about a week ago. It was using an OpenVPN server hosted in a US Datacenter and the VPN clients were simply routers with third party Linux firmware with the OpenVPN client embedded in the firmware.

I am also investigating the possibility of tunnelling OpenVPN through SSH but I have to watch my IP overheads here because the ISP watches the upload bandwidth as well!

Has anyone attempted or had any success using stunnel for a similar scenario as I have mentioned?

Thanks in Advance

Regards,

Errol
