So lately I’ve been working on the Isilon quite a bit and we have a couple PAC servers that travel through the Netscalers here in our environment.
These netscalers are used as the Server’s default gateway for routing traffic. However using them as a source to route all data isn’t a great thing to do from a performance perspective, So some static routes are created to help make it’s backend NAS connections a bit faster.
First execute “Route Print” and note the Interface number, in this case 12,11,13,14,1
12…02 00 4c 4f 4f 50 ……Npcap Loopback Adapter
11…ec b1 d7 3d 7d 8e ……Intel(R) Ethernet Connection I217-LM
13…00 50 56 c0 00 01 ……VMware Virtual Ethernet Adapter for VMnet1
14…00 50 56 c0 00 08 ……VMware Virtual Ethernet Adapter for VMnet8
1………………………Software Loopback Interface 1
We would like to target 11 in this case.
Also note we need the word “MASK” in the middle or the command will not be parsed correctly
Giving -p for a persistent change, All connections to 10.246.x.240 will not route through 10.246.x.1
route -p add 10.246.x.240 MASK 255.255.255.255 10.246.x.1 METRIC 1 IF 11
route -p add 10.246.x.241 MASK 255.255.255.255 10.246.x.1 METRIC 1 IF 11
route -p add 10.246.x.242 MASK 255.255.255.255 10.246.x.1 METRIC 1 IF 11
route -p add 10.246.x.243 MASK 255.255.255.255 10.246.x.1 METRIC 1 IF 11
