Can’t ping
each other in a Demand Dial VPN
Remote router no
the return static route
Q1:
I have a pressing networking issue, and I've tried everything to get it
running.
The end result must be that computers on the local network can access a
server via TCP which is located in a
remote network which is running a
PPTP server.
The solution I can see without destroying the existing network is to drop a
new box running RRAS into the network, use demand dial to connect to the
remote VPN, and route
LAN traffic over that box.
Here's a picture of my current setup
Local LAN
192.168.1.0/24
______|_______________________

Router RRAS Box
Test Client
192.168.1.1 192.168.1.3 192.168.1.103
| | GW: 192.168.1.1
Internet Remote Site
x.x.x.x 192.168.0.0/24
|
Remote Server
192.168.0.3
Currently I have the setup I've mentioned above, and have setup a static
route on the LAN Router (192.168.1.1)
192.168.0.0/24 --> 192.168.1.3
From the RRAS server I can ping devices on the 192.168.0.0 network
The problem I'm having is when I do a ping from the test client I get no
response, when I do a trace route I get the path
192.168.1.1
|
192.168.1.3

*********
From my perspective it looks like the traffic is getting sent to the server,
but is not passing.
The server is a fresh install, stock config, no
domain and I've simply followed
the wizard to setup the demand dial VPN.
Never having done this before I've reached the end of my knowledge and am in
need of an expert.
Please let me know if you have a potential solution.
Thank you,
Lee
Another note,
The default gateway of the RRAS box is the 192.168.1.1 router.
Not sure if that matters, but it is the preferable configuration.

Sounds
like routing issue. have you enabled the IP routing? this troubleshooting

Q2:
I agree, it looks to be a routing issue. It definitely looks like it cannot
route between the virtual WAN adapter and the local LAN adapter.
"Enable IP routing" is checked. I've seen that document in my searches, and
I've tried their recommendations. Unless I'm missing something obvious.
I'd love to attach some screen shots for you guys, is there a way with this
forum, or do I need to post them on a web-site and link to them?
A2:
Posting the routing table here may help.
Q3:
The problem was
that the routing table on the remote server was lacking the return static
route.
