Re: VPN PPTP Ping traffic one way only?

Tech-Archive recommends: Fix windows errors by optimizing your registry


I have exactly the same problem. SBS 2003 Premium SP1 with ISA 2000.

Once the VPN client is connected it is unable to ping the server by ip,
netbios name or fqdn.

Tried from different client computers, using different internet
connections, same thing.

My ipconfig when I connect from this remote workstation is:

PPP adapter ROSCO:

Connection-specific DNS Suffix . :
Description . . . . . . . . . . . : WAN (PPP/SLIP) Interface
Physical Address. . . . . . . . . : 00-53-45-00-00-00
Dhcp Enabled. . . . . . . . . . . : No
IP Address. . . . . . . . . . . . : 192.168.16.18
Subnet Mask . . . . . . . . . . . : 255.255.255.255
Default Gateway . . . . . . . . . : 192.168.16.18
DNS Servers . . . . . . . . . . . : 192.168.16.2

The server IP is 192.168.16.19 if looking at the details of the VPN
connection.

Hi All,

The setup is an SBS2003 with all service packs (microsoft update)
running
ISA 2000. We use RRAS for PPTP VPN clients. It had all been working
fine for
acouple of years. What happens is a client can happly establish a VPN
connection but cannot ping the server, either the IP address bound as
the
RRAS adapter or the actual LAN IP of the server. The server or other
computers on the work network can ping the connected VPN client. I
assuming
its some sort of routing/binding problem but cannot figure it out? as
if I
can ping one way why not the other. There isn't any filtering in RRAS.
I've
reinstall RRAS twice, ran the internet connection wizard but still no
joy. It
is behind a watchgaurd firewall which is passing through the PPTP
traffic
fine. I've compared ISA to another working client and can't fine any
difference. Nothing had changed on the SBS box or the firewall and now
we got
this problem. Even pinging with 1 byte of traffic doesn't work.
HELP!?!?

Regards,

Brett
