RE: IPSec and GRE (47)

I don't understand the question but the tcp port used for gre is: tcp 1723.

Try open this port

Subject: IPSec and GRE (47)

Hello,

I want to configure a Windows 2003 server machine, which provides remote
access.
This server should be protected using "IPSec".

In the IPSec mmc I cannot use protocol 47 (GRE). If I use the IPSec filter
from RAS, I can select this protocol.
But because I want to manage the "firewall" from the IPSec mmc, I have to
configure it there.

Do I have to use command shell to configure IPSec that way?


Thanks,
Thomas
