I have a Virtual Dedicated Server with 6 IP Addresses. 1 for the server and 5 for other websites.
I want to block the access to port 9999(control panel) and 22(SSH) for all IP Addresses except 1.
They are internal IP Addresses not external.

So w1.x1.y1.z1:9999 is accessible but
w2.x2.y2.z2:9999
w3.x3.y3.z3:9999
w4.x4.y4.z4:9999
w5.x5.y5.z5:9999
w6.x6.y6.z6:9999
do not work. Please help

I plan to use ipTables to do so since I am using it currently to block ports 993 and 995

Also, I plan to add more IP Addresses later to the same server.
SO I would prefer a rule which would allow access to w1.x1.y1.z1:9999
instead of writing 5 rules to deny access to other IP Addresses, so that I dont have write new rules when I add another IP Address.

Although this is just preference. Any rule works fine for the time being.

Please help.

Not a problem, what do you already have written for your rules?

I used this:
iptables -A INPUT -p TCP -d ! w1.x1.y1.z1 --dport 22 -j REJECT
iptables -A INPUT -p TCP -d ! w1.x1.y1.z1 --dport 9999 -j REJECT
