Occasionally I have to set up a lab environment for testing and in the past I used static routes configured on the Comcast supplied Netgear firewall/modem to all access to the various lab subnets. I haven’t had to use the lab environment for several months and discovered that traffic using the static routes is now unreliable where it used to flow as expected.
Was there a firmware update that negatively impacted static routes? I saw another post that the static route functionality on the Comcast Cisco BWG was not working.
If I add a static route on a Windows box sitting on the 10.1.10.0 network to use 10.1.10.200 as the gateway for my lab subnets, traffic flows fine. When I use the Netgear device to route the traffic, traffic flow is unreliable.
My configuration is:
10.1.10.0/24 network hanging off Netgear device => Router (10.1.10.200) => various subnets (ie 10.1.50.0/24, 10.1.60.0/24, 10.1.70.0/24)
Netgear static routes:
Name Destination IP Subnet Mask Gateway IP
10.1.50.0 10.1.50.0 255.255.255.0 10.1.10.200
10.1.60.0 10.1.60.0 255.255.255.0 10.1.10.200
10.1.70.0 10.1.70.0 255.255.255.0 10.1.10.200
This is what I get when using static routes on the Netgear device:
