Two NIC - one for cache, one for Internet

[Ollem]

Hey kind visitor

 

I upgraded my PC (Win 10) and my FreeNAS with a second NIC. Most of what I tryed to do works so far but my loadingtime in the internet is not great. Probably because every query in my Browser goes first head on into my dead end.

 

NIC A = 10gig -> my upgrade

NIC B = 1gig -> onboard

 

On my PC I setup the NIC's like the following:

NIC A has priority over NIC B

NIC A 192.168.2.60 -> Gateway to 192.168.2.65 (FreeNAS)

NIC B 192.168.1.108 (DHCP) -> Gateway to 192.168.1.1 (Router)

 

What I think that happens with every query:

I open a website, the browser tells NIC A to go to the Website's IP -> NIC A can't go to the internet because FreeNAS isn't connected with my router -> then the query goes over NIC B and connects successfully.

That takes some time, with every query.

 

The reason why I've setup like this:

Caching downloads on FreeNAS (on a VM with docker but that should be a different topic, it already worked but with the slow NIC B) so when I download it, the query should go first to the FreeNAS over NIC A. If there is no cache, it should connect with NIC B to the external Servers. The setup of Lancache isn't finished yet, so I couldn't try if my plan works like this. 

Or is there a much easyer way to setup the network to cache with NIC A and get quick loading times in my Browser with NIC B?

 

Any help is appriciated

 

Cheers

Check your routing table (`route`). The default route (0.0.0.0/0) should have your router (192.168.1.1) as the gateway. You can also try running traceroute (for example to Google DNS at 8.8.8.8 or CloudFlare at 1.1.1.1) to see the path/hops that packets take.

Sweet, I didn't know there is such a easy way to get the path.

 

I'll check this as soon as I'm done with work.

 

Thanks alot

Well, quick update:

 

I was able to test the tracert 8.8.8.8 but the rout went straight ou of my network but took 1 min 18 sec to reach google after 11 hops.

 

 

I don't know if that's normal but I can't see if it trys my NAS first or not.

 

I'll keep testing and trying.

I'd think what you would need to do here is have it access FreeNAS over the normal LAN but have the Cache return the IP address of the second NIC on FreeNAS so that when your PC tries to actually pull the data it goes over the faster connection completely ignoring the default route.  I have no idea if your cache can be configured that way.

Obviously ideally, you'd just stick the PC and FreeNAS on a 10Gbit switch to make it simpler.
