also,
I was looking for the same information and found loads of different answers
on google, etc. These are some notes I made at the time.
Netgear tech support:
ports 1723 and 500.
Newsgroups:
1723 for PPTP
500 - IPSec ?
50
51 for IPSec.
groups.google
port UDP 500 if using key neg (IPSec?)
port UDP 1723 for PPTP
Protocol 50 ESP (not port number, but protocol)
Protocol 51 AH?
PPTP: use port 1723 and GRE protocol 47 (Generic Routing Ecapsulation
protocol)
L2TP: ports 1701 and port 500
then my notes say: "check some books".
I've got both of mine in the 'DMZ' (i.e. all ports are open and all packets
are forwarded to the FVS318 now).
I actually have 3 sites with these units and find that even thought all
ports are open on all sites and all the sites' FVS318's report a fully
established connection that 1 of the sites does not work properly - e.g.
network browse and ping don't work - actually nothing that you'd like to do
over a network actually works with this site (in either direction). Some
packet sniffers at various points on the way indicated a problem with an
intervening corporate ISP provider mangling the encrypted VPN packets - e.g.
modifying the source or destination IP address and sending the modified
packet on, but then sending on the original as well - stuff like that. They
currently have their firewall vendor looking into the problem - so things
can screw up in realms outside of your control.
