Hello All,
Great Firewall of china is blocking all IPSec ports 5400 & 500 because of which we are not able to form any site to site VPN in sites iin china..
Is there any workaround for the same to make it work..
I am using cisco routers from remote end as well as Hub end..
Regards,
Ranjit

Never tried it, but you could use IPsec over GRE.
Here is a config I was able to find:

I managed to get the IPsec over GRE to work, but it seems like all IPsec came back up suddenly just after New Year.
