In this case, I would recommend using Forefront TMG as a firewall. This is because it has an ISP Redundancy feature that be used to configure to ISP WAN connections using:
Another option is to have a router that will have such ability. This router will be place in the location showed in the following picture.
how it will work all client will get internet from DSL modem? but we have some site which can`t not be accessible from public IP i don`t want to give the all client to access internet few of them will be use 20Mbps i`m rely out of mind coz i don`t know much about routing
OK then in this case, you will need a router that should be able to route traffic based on the source IP / VLAN. If you want to have a CISCO equipment, you can ask them in CISCO forums for more details:https://supportforums.cisco.com/index.jspa
You have few options here. Although it depends on your environment. Do you have a Cisco router? your picture doestn indicate anything. However, if you do have a Cisco router, you can use PBR based on originating address.
I guess you should give a more clear view of your network.
We don`t have Router but we have switches I’m new in this work and i will upload network diagram
The thing is i want to use this 20Mbps in my network what i was thinking before is i will make secondary DNS and it will work but when i got DSL line I’m stuck how to configure it
If you are using a 2960 switch which is a layer 2 switch and you dont have a router either, then your options are limited.
If you have signle Vlan for all your hosts, then you can simply plug the new line into your switch and configure your DHCP server to static entries for those clients to get the new line's ip address as their default gateways.
If you have multiple Vlans, (which I doubt because you said you dont have a router nor is your switch a layer 3), then you can simple have proper subnetting and relay -agent configured to hand the hosts right default gateways.
