Routing and Remote access Assigning wrong DNS IP


T

TheWall

Hi, Our VPN via Win2k3 Routing and Remote Access was working 100%.

Now suddenly clients get the wrong DNS IP. They get 10.10.0.180 but is
suppose to get 10.10.10.150.

Where does it get this from? How can i change it?

Typically, if you're running DHCP on your network, RRAS will reserve a group
of IPs from your DHCP server for use with vpn connections. You may want to
check your DHCP server to see what has been reserved for your RRAS services.
Of course, you could also manually set an IP block to be given to your
remote connections manually through RRAS if you are not running DHCP.

My experience in the past has been where I had one RRAS server running and
it reserved a block of address from my DHCP server. Then, something happend
with the RRAS server and I reinstalled it or I plugged in a new RRAS server
and it would reserve a new block from the DHCP server while all the while
the old reserved block is sitll reserved on the DHCP server. You may want to
look into the same situation if you have reinstalled your RRAS server or had
an additional RRAS server on your network. When you look at your DHCP
leases, you'll be able to see which ones were reserved for RRAS.

Hi, i have moved the RRAS from our Domain Controller the the server it is
currently hosted on. Was working for about a week and not it started handing
out the wrong IP.


In the DHCP i dont see any reservations?
So there is nowhere on the server where i can just change the Primary DNS
server to what i want it?

I have found that about 20% of the servers I have set up with RRA do not
work as a good DHCP server. Some will give wrong DNS and some will give
none..
So, Add Remove Programs, Windows Components, Networking, DHCP, set up a
scope and add the dns, route, etc.. Everything works fine.

I know PPP has BAP but I think that is for dial up type of things.

I would like to have to "Public interfaces"... two WAN ports... Both acting
as one, doubling the speed and providing redundancy.

This may be able to be done through PPP by just setting up two PPPoE, but I
just want to know if someone has done it before and if it work..
If not, I will have to buy a D-Link DI-LB604 10/100Mbps Load Balancing
Router 2 x 10/100Mbps WAN Ports 4 x 10/100Mbps LAN Ports but I have found
RRA to be so much faster than any store bought router!

In RRAS you can set which DHCP server to use. I can't remember where off
hand but it isn't hard to find if you look around.

Hi Dean.

I personally do not know if win2k RRAS service will do load balancing with
two lines. I've never done it and never heard of it being done. You may want
to post your question top level though so everyone here can see it.

Hi Dean,

So what you are saying is that i must create another DHCP Server? It is not
wise having 2 DHCP servers in one network not true?

Not only does it make no sense to have two active DHCP servers on the same
network, it would also cause all kinds of problems.
