In a city center with a lot of tourists from abroad we do wish to offer a free and unencrypted Wi-Fi service. We expect 800 new devices per day (up to 100 concurrent).
The LAN segment of Balance 310 rev.2 is using a 192.168.1.x class C. Our current DHCP setting has a TTL of 14 days. That would collide quickly. We could reduce the lease time to 1 hour, and have a load of extra broadcast traffic.
Another idea is to setup a new class B VLAN for wireless guest access, f.e. 172.16.0.0/16, to have 65 thousand of IP addresses, or even a class A 10.0.0.0/8 with 16 million private IPv4 addresses.
Would the Balance 310 rev.2 its internal DHCP server be capable to handle a DHCP list of 8000 entries?
Or should we offload that to a separate DHCP server?
What would be a practical upper limit of the address pool size a Balance 310 DHCP server is able to handle?
