Hello guys. I have been using this vpn and i love it. But to my surprise i have depleted all the IP's in the system, NOW WHEM I TRY GENERATING NEW IP I GET The subnet configured supports only 253 clients.. I WAS THINKING TO ADD A NEW INTERFACE I.E WG1 to the system but not sure if it will work or expand the subnet to /21. Any one with an idea how to go about it or someone who has done the same. Kindly assist here. Here is may wg1 sample,

[Interface]

ListenPort = 56XX0  
PrivateKey = KIcer+xxxxxxxxxxxxxxxxxxxxxxKTMz9nU+lk=
PostUp = iptables -I INPUT -p udp --dport 5XXX0 -j ACCEPT
PostUp = iptables -I FORWARD -i eth0 -o wg1 -j ACCEPT
PostUp = iptables -I FORWARD -i wg1 -j ACCEPT
PostUp = iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
PostDown = iptables -D INPUT -p udp --dport 5XXX0 -j ACCEPT
