Is ISP Redaundancy possible with Only 1 external and 1 internal NICs?
I Have 1 external NIC , 1 Internal NIC, 2 Internet connections and a Cisco Switch.
Can I Use ISP redundancy feature with the mentioned resources?
NIC 1 Configuration: (External)
IP: 192.168.1.2
Gateway: 192.168.1.1 (Modem 1 with Internet connection 1)
NIC 2 Configuration: (Internal)
IP: 172.18.1.2
Gateway: None
I'm thinking something like this:
1. Connect both NICs to the switch
2. Connect both Modems (2 internet connections) to the switch
3. NIC 1 Config remains unchanged
4. NIC 2 Gateway changes to Modem 2 IP (172.18.1.1)

Thanks to all who replied.
My switch is just a layer 2 switch --> No routing done by the switch.
My 2 connections are from the same ISP , So what I really want to do is load balance between my 2 NICs
My idea was that TMG would do the routing , not the switch.
Check the image attached:
Packets to 172.16.0.0/16 would be forwarded to 172.18.1.12 (Modem 2)
Other Would be forwarded to 192.168.1.1 (Modem 1)
This has been tested and it works.
I just wanted to load balance between my 2 NICs instead of statically assigning routes like this.

I searched our warehouse for something useful.
I found a CISCO RV042 router in a good working condition , What is more awesome is that I found that it supports Dual WAN for load balancing.
I decided to configure and integrate it in my network.
I watched a video for configuring DUAL WAN but it was not clear for me how should I configure IP interfaces for both the router and my TMG.
Please see the attached Image.
In my scenario can anyone advise me how to configure IP interfaces on both Router and TMG (IP, Gateway)

Do you have two ISPs connected to your network?
OR
U are talking about NIC redundancy meaning, if one NIC fails, 2nd nic will connect to ISP?
