full networking newb right here, so I am fairly outdoors of my consolation zone, however I’ve just a little homelab I am toying with and was questioning if it is potential to arrange a secondary community that is fully separate from the first one.
See, I wanna use a server of mine to host a pair tasks on-line, and to my data, that would open up my community to attackers. So, I believed I ought to arrange a subnet for that server in order to not expose the remainder of the purchasers on my community. Situation is, my change is unmanaged ( 🙁 ) which suggests I can not arrange subnets (proper?). So, as a result of I can not presently afford shopping for a brand new change, I believed I’d be capable of use a second router I had laying round to do the trick…
I’ve managed to alter my router’s (mi router 4c) firmware from inventory to the most recent OpenWRT, and it is working high quality. I’ve managed to get each routers (main one offered by my ISP is a Speedport Plus 2 which so far as I can inform would not assist subnets with it is inventory firmware and I do not really feel comfy altering it is firmware to OpenWRT for ISP-related causes – a.okay.a. I do not wanna get in bother…) to work on totally different networks, main one being the default 192.168.1.x and secondary being 192.168.2.x. Main community is not bothered by any modifications I make on the secondary one, which I consider is predicted conduct. On the secondary community although, I am unsure methods to isolate it from the primary. I can both get web connection but in addition be capable of see units of the first community, or I can not entry units on the first community but in addition haven’t got web connectivity…
Is what I am attempting to do even potential? Whether it is, might anybody assist me perceive what I am doing improper? Is all this well worth the effort, or will my setup nonetheless be not safe, if it is potential and I can handle to get it to work?
I perceive that my greatest guess could be to simply purchase a brand new change, however I would prefer to keep away from it as a result of I would want minimal 24 ports and assist for speeds over 100mbps (presently operating FTTH 200mbps, may improve sooner or later if vital), and people unhealthy boys can get costly the place I am at, except I have been to purchase a less expensive 8-port one and plug my present change on it for one of many subnets, however i do not know if that is a great method..?
TYSM upfront for yall’s time ^^
