i configured a VPN server with IPSec to surfe secure at public networks. At generally it works. Now i would like to access my vpn server from my campus. Here i can't get any connection.
I know, that the campus administrator block all ports under 1024 except http and https. I also know, that IPSec use UDP 500 and 4500.
- Do you think it is enough to change the port UDP 500 to a higher port? Are there other ports important for IPSec under 1024?
- Does IPSec work with TCP instead UDP?
