hi . in 1 virtualhub i configured ip addresses list like this

192.168.31.255

when the online users reach the 255 session its mean 30s ip block is full and got ip from 31s block , the userswith 31 ip range are online but no data transfer ! how can i fix this ?

for example the user has ip 192.168.31.3 is online but cant get any data

when the online users reach the 255 session...

The use of authentic UNIX or Windows DHCP server software is recommended where the Virtual DHCP Server functions are insufficient.

I see, here are alternatives for SecureNAT (vDHCP/vNAT):
- on Windows Server edition these components already exist (RRAS + DHCP)
- on Linux simply use iptables + dnsmasq

problem solved by just editing subnet mask to 255.255.254.0
