IP Routing

[DarraghFitzpatrick]

Scenario

Remote Office
10 wrkstns
100Mb Switch
DSL Modem - 1.1 MB
Fractional T1 at same location.


Each wrkstn uses currently uses a citrix client to connect over the DSL line to a citrix server at out main office.

I want to setup the following scenario

New Scenario

10 wrkstns
100mb Switch
Router
(The router splits traffic between the DSL conection adn the Fractional T1). I do not want to set up a form of load balancing. I want the traffix to be split depending on the type of traffic it is. i.e. ICA traffic sent over the T1, all other traffic sent over the DSL conection.

What family of Routers should I look at.

The 1721 should cope with this, the WAN line speeds are not that high.

You will need to get a feature set that supports policy routing, as this is they way to make the forwarding decisions based on traffic type. Also support for the fractional T1, I'm sure that is supported in this family.

The T1 card to look at is WIC-1DSU-T1-V, how are you connecting to the DSL in the new set up?

You would need to use IOS 12.3.1 or later to support all the required features, this includes Netflow support for policy routing.

Actually, the T1 is plugged into a Netopia router. The provider supplies this, I wish to keep it for support reason with the line.
Both the DSL and T1 will be connected to the router using std ethernet cable to WAN ports.

I'd look for something with dual ethernet interfaces..


Then set the router up to use NAT to go out of one of the ethernet interfaces to the internet, then use a T1 link back to the site for the citrix..

This would be easy to setup and doesn't take much gear to accomplish this..

In that case you wouldnt need to use PBR, if the DSL is to the Internet and the T1 is purely internal traffic then the internal routing will do what you want.

 

[DarraghFitzpatrick]

Internal routing will only functiun, if I set a VPN over the T1 correct ?

 

[routerman]

I dont understand the comment. What I meant by `internal routing will do what you want' is that you will have a default route pointing to the Internet, and specific static or dynamically learnt routes to the location where the citrix servers are located.
That way, if your router receives a packet for Citrix, it will have a specific route for that location and will know to send it over the T1. If its an Internet address, then
no specifc route will exist, so it goes via the default route which points out via the DSL. As BuckWeet pointed out, this will use NAT to translate your internal private address to a real world address.

There is no need for any VPN
