IP Subnetting Question

[yasockie]

A couple of comments:

What's the up speed on the ADSL - A stands for Asynchronous for a good reason - the up speed even on business lines are 1-2 mbit at best, so 18mbit is a huge step up plus I assume fiber is more reliable than noisy copper lines.

Second this is you're really stingy with the IP address allocation - they are you private IPs so why not assign at least one whole class C subnet such as 192.168.1.x to one network and 192,168.2.x to the other - in this case the 255.255.255.0 mask is fine and easier to remember. By splitting a single subnet you only get 125 or so usable addresses which might seem like a lot, until you start doing a lot of automated testing with lots of VMs.
Also consider having some local hostnames/DNS or AD set up - and refer to your devices using that.

I use Free Network Monitoring Software | Spiceworks Free Network Management Software for network monitoring....very interesting piece of free kit too.

My ADSL up is 1mbps which is probably more than I need in 95%+ of situations and the other 5% aren't important enough for me to care. As long as I can VPN in and get a robust RDP session out then I'm happy (edit: as the most latency and bandwidth sensitive thing)

I prefer single subnets as then it's a simple matter of splitting the last octet around. I doubt I'll ever need more than 50 addresses, even with the multiple VMs I use; I have my DHCP lease expiry set at 1 week so I'd need to be going something to go through the 40 addresses in the range.
