new network layout ideas

can you please clarify if it is a two-way or one-way communication between the two subnets?

FYI -  your access to the Internet is one-way, not two-way, because the external hosts on the Internet can't access your internal devices.

On network 1.
Router subnet 10.10.10.100/24, this is acting as we speak

Second network , i haven't done yet
But if i at least get access from network 1 to 2 via RDP , that be great

per your situation and access requirement, i don't see the point to have two subnets at all.
you may simply change the DHCP settings on the server to release IPs for subnet one, then all client devices will be working on the same 10.10.10.x network.

Unfortunately lightning struck my house and took down my network architecture for good

I assume you've addressed grounds, surge protection or the lack there of?

I get, it it's much simplistic to have just one subnet to rule them all from the  windows server , just like a has before.
But from my experience troubleshooting and getting back on my feet, it took me so long, as opposed if they were independent networks then it would be much faster , considering that i work from home

And yes i did took care of my grounds now , before  i have 6 surge ups protectors but since the problem i had, it was the coaxial modem to cause the  issue and then hit all my devices via Ethernet....
Now i have grounds on my coaxial and Ethernet connection

By the way if like to mention if anybody like to draw any solutions ideas those are welcome too as i am more of a visual guy 🙂
I use a free website for my drawings

You need at least a router on the network to separate the different subnets, or maybe a firewall if you want more restrictive communication between the two networks.

Router can be physical, or a VM.

I am too lazy to draw you a picture...

Thank you All. for giving me ideas.
now its time to for me to do some research on a router that has an IP Helper ...

Anything above a home router should have DHCP relay.

if you are happy with Richard's design then you need to find an L3 switch, which is not that common for home Wi-Fi routers. this feature is commonly seen in advanced routers in Small Business and Enterprise categories, and of course, expensive than the Home devices.

I use a Cisco SG350-10 10-Port Gigabit Managed Switch.

However it looks like this has gone EOL - with a replacement being the Cisco CBS350-8T-E-2G

They cost around £200 (UK) and should do everything you need.

@richard does one need to buy a license with this switch, or year subscription maintenance?

For the SG350-10 - then no. 

It’s one of the few Cisco devices that do not require a license or maintenance payment to have access to all features and firmware updates. 

Having looked at the newer version (CBS350-8T-E-2G) - again the firmware is available without a login, and I can find no mention of any features requiring a separate license. 

Closing the loop on this.

I think the CISCO appliance would it been an excellent choice,  however considering the investment and the duty of it here, I opted to create a virtual machine, using pfsense which is free, I only had to purchase a PCI card with two nics,  and a hub . the pfsense allows me to create vlans and pretty much everything in between though, so much power on the software side I'm only using it as a gateway. lol

I Ended up with this:

it was worth the exercise as I learned a lot 

Thanks for everyone involved here, and I am going to keep that CISCO CBS350-8T-E-2G in mind If I ever do something professionally, I consulted with them, and here in the US is not that bad for pricing and they told me no need for subscriptions either
