That makes no sense to me. With NAT removed from the configs you posted I'm not seeing anything jump out at me as to why you are having an issue unless it's something outside of these two routers assuming the current config of the routers is correct based on the rest of the corporate network.

Are you sure the mask you used for 131.107 on the corp router is correct? Based on the mask you used you are telling the router that all of 131.107.x.x is the same segment. No other segments handled by other routers. I see you have 131.107.15.5 as the IP address on the router at corp but you also have a helper of 131.107.1.14 on the remote. Are 131.107.15 and 131.107.1 really separate IP segments. If so, there is work to do on the corporate side of your network.]]> http://www.dslreports.com/forum/remark,22711138 Wed, 15 Jul 2009 10:44:03 EDT http://www.dslreports.com/forum/remark,22701426 Necrofuzzy : We turned off the nat on the remote side. Dont know why we had it on in the first place. From corp we can ping the router and a machine connected to the router via switch, But from the remote machine we cannot ping or communicate with the network that is connected to the router on corporate side, even though they have the same settings. i.e
next hop for the remote router is 10.10.52.1(interna)
and a route from 131.107.15.5(the corp router) for a network here at corp is 131.107.0.0 255.255.0.0 has been added.

and here on the corp side the next hop is 10.10.52.2(internal)
and a route from 192.168.200.1(remote router)
and that route =
192.168.200.0 255.255.255.0 to 131.107.15.5]]> http://www.dslreports.com/forum/remark,22701426 Mon, 13 Jul 2009 16:49:13 EDT http://www.dslreports.com/forum/remark,22680725 Necrofuzzy : Well like i said we really are new to this. And why would we not want the connection to be permanent. Its a direct T1, doesnt go through the internet. Its purpose is to have the remote office connect to our servers and log into our domain.
Should we not make it permanent? If not, please tell why?]]> http://www.dslreports.com/forum/remark,22680725 Thu, 09 Jul 2009 14:32:52 EDT http://www.dslreports.com/forum/remark,22678372 aryoba : 1. Is there a reason why the remote office router does NAT?

2. Why do you want route on corp router to reach remote office to be permanent?]]> http://www.dslreports.com/forum/remark,22678372 Thu, 09 Jul 2009 09:25:17 EDT http://www.dslreports.com/forum/remark,22678315 Necrofuzzy : I posted my configurations.

like i said we are complete noobs at this. Hope you can help us with this.]]> http://www.dslreports.com/forum/remark,22660542 Mon, 06 Jul 2009 11:08:35 EDT http://www.dslreports.com/forum/remark,22640136 carp : remote site router should have statement:

ip route 0.0.0.0 0.0.0.0 10.10.52.1

corp:

ip route 192.168.200.0 255.255.255.0(or your actual mask) 10.10.52.2

make sure the other devices on 131.107.1.5 have the correct default gateway or the default gateway they point to has correct routing for the rest of the network.

or post your router configurations.]]> http://www.dslreports.com/forum/remark,22640136 Wed, 01 Jul 2009 14:34:12 EDT http://www.dslreports.com/forum/remark,22639783 rsaturns : I would suspect routing. Does the Corporate site network know how to route back to the 192.168.200 network? You can ping the 131.107.15.5 because that router knows about the 192.168.200 network because I assume you assigned it a static route.

You would need to tell the router in the 131.107.x.x how to route back to the 192.168.200 network.

pc with static ip of 192.168.200.20 is connected to:

router remote side
----------------------
Remote site fastethernet ip = 192.168.200.1
remote site serialT1 ip = 10.10.52.2

corporate site serialT1 = 10.10.52.1
corporate site fastethernet ip = 131.107.15.5

that is plugged into our main network wich is 131.107.x.x

our dhcp server is 131.107.1.14
our domain server is 131.107.1.5

from remote site we can ping the 131.107.15.5 but not the rest of the network.

??? any ideas why?

Is it something we can do with sdm, (sad) thats what were trying to set it up with. Were noobs . :huh:]]> http://www.dslreports.com/forum/remark,22635724 Tue, 30 Jun 2009 16:38:57 EDT http://www.dslreports.com/forum/remark,22635582 rsaturns : Basically you need to take the following steps.

Setup the serial interface on each 1841. If this is a true private point to point you can use whatever IP address you want highly recommend a /30 as to save address space.

Once you can ping across the T1 you’ll need to make sure that the network on the Corp side of the link is aware of the network on the far side aka a route either statically assigned or using some sort of dynamic routing protocol.

Next setup your Fast Ethernet interface on the remote site with the network subnet of your choosing make sure again from Corp you can reach that side of the far router.

Setup an IP helper *address* on that fast Ethernet interface and point it to your DHCP server back at Corp.

Make sure Corp has a scope for this remote network.

That’s the process in a nutshell with a lot of detail omitted.

Edited to say ip helper address not interface.

We have a T1 line running from our current office to a remote site. We have 2 1841 cisco routers to connect to each side.
We use a NT domain and assign ip addresses dynamically, on the office side. We would like to assign the addresses from the same dhcp server to the remote site. But first we need specific instructions on how to set up both routers. We have tried using sdm express but havent had much luck.
