RRAS LAN to LAN

January 23, 2008

I will be brief and hopefully someone can help. I have a Server 2003 box,

mulithomed 2 NICs. I have set up RRAS for the LAN config, and on one NIC I

have a switch with a few nodes and on the other NIC I have another switch on

the other LAN side. My IP configuration is this NIC 1 has an address of

192.168.200.5 mask 255.255.255.0 and on the other NIC I have 192.168.1.50

mask 255.255.255.0 and gateway 192.168.1.1 and they are all /24. I have a

test box configured on the 192.168.200.0 network with IP configuration

192.168.200.3 mask 255.255.255.0 Gateway 192.168.200.5 which is the IP of the

NIC on the RRAS server for that lan. I am unable to ping anything in the

192.168.1.0 Network here is route print for that box:

Active Routes:

Network Destination Netmask Gateway Interface Metric

0.0.0.0 0.0.0.0 192.168.200.5 192.168.200.3 20

127.0.0.0 255.0.0.0 127.0.0.1 127.0.0.1 1

192.168.1.0 255.255.255.0 192.168.200.5 192.168.200.3 2

192.168.200.0 255.255.255.0 192.168.200.3 192.168.200.3 20

192.168.200.3 255.255.255.255 127.0.0.1 127.0.0.1 20

192.168.200.255 255.255.255.255 192.168.200.3 192.168.200.3 20

224.0.0.0 240.0.0.0 192.168.200.3 192.168.200.3 20

255.255.255.255 255.255.255.255 192.168.200.3 192.168.200.3 1

Default Gateway: 192.168.200.5

However I can ping anything on the 192.168.200.0 network from the

192.168.1.0 network by adding a route add statement

route add 192.168.200.0 mask 255.255.255.0 192.168.1.50

Can anyone help me as to what I am missing here?????

Re: RRAS LAN to LAN

Assuming you have enable IP routing, I would check the Input and Output

Filters. Or check the NAT/firewall if you enable them.

NAT and FirewallOpen RRAS>IP Routing>NAT, right-click external

NIC>Properties>Services and ... 6) IP packet filtering is preventing the

receiving or sending of IP traffic. ...

Re: RRAS LAN to LAN

I set up RRAS and NAT is not in the equation. This should be quite simple, I

am pulling my hair out. This is LAN/LAN routing on W2k3 RRAS. 2 Networks

192.168.1.0/24 and my new network 192.168.200.0/24...I cannot ping anyting on

the 192.168.1.0 network from the test host 192.168.200.3. I did a route add

on the test machine 192.168.1.0 255.255.255.0 192.168.200.5 ....Uggghhhh!

Still No replies. What am I missing here??? I can ping both sides from the

RRAS server, and if I add a route add to a node on the 192.168.1.0 side I can

see the new subnet (192.168.200.0)...why cant anything on the 192.168.200.0

netowork see anything on the 192.168.1.0 network??? Help Please
