- The port services for PPTP and L2TP gateway, as
well for IKE Security are open. And it's like I wrote in the previous message:
The VPN server doesn't accept any connection to the firewalled interface over
any protocol, including a telnet session to this interface over PPTP port 2723
(the connection fails).
- Have also installed Hotfix 897651, doesn't solve
the problem as well.
Thank you all in advance for any further
advice

"when adding the public interface to the "NAT/Basic
firewall"
category, the server doesn't accept inbound connections anymore,
even when
adding inbound and outbound filter rules that allow connections
from any
to any over any protocol" Have you check the port services? Or do
a simple test to telnet port 1723.
Have
a problem with a Windows 2003 VPN RRAS Server. RRAS is configured as
"VPN Remote Access Server only", allowing only IPSEC/L2TP inbound
connections and enabling the Basic Firewall (without NAT) on the public
interface.
The server works fine, until SP1 installation. After
that, the VPN Server
doesn't accept inbound connections anymore. Have
found that the problem is
releated to the Basic RRAS Firewall. When
removing the public interface from
the "NAT/Basic Firewall" category,
the VPN Server accepts inbound
connections. But when adding the public
interface to the "NAT/Basic
firewall" category, the server doesn't
accept inbound connections anymore,
even when adding inbound and
outbound filter rules that allow connections
from any to any over any
protocol, and enabling all ICMP protocol rules.
It's also not possible
to ping the external interface from a external
client.
When
removing the public interface from "NAT/Basic firewall", inbound
connections work fine. Inbound connections also work fine when removing
SP1,
with enabled firewalled public interface. Have installed SP1 tcp/ip
hotfix
898060, no success. It's not a problem particular to one machine,
I was able
to reproduce the problem with two virtual machines on my
Notebook.
Thanks all in advance for any help or advice
