Hi all i am stuck on this VLSM subnetting,

you have been allocated one public class C 195.100.190.0/24 the internal must use Private Addresses the pppublic license will be userd for NAT Mapping, THE ISP WAN that connects to the Customers Site uses network address 199.1.1.36/30 and for the ISP Loop Back port use IP address 126.0.0.1/8

Using VLSM plans for approximately 15 hosts on R2 & R3 7 Lans at R5 and 5 Lans on R6. Assign the First useable IP address to the Router Interface and the last usable IP to the host device

Config NAT on R1 to translate between Private and public addresses the web servers hosts the enterprise web business and therefore must have a fixed address assignment.


199.1.1.36/30

i assign the following

R2 - Max 30host

199.1.1.37 - 199.1.1.69 SN 255.2555.255.224

R3 - Max 30host

199.1.1.70 - 199.1.1.102 - SN 255.255.255.224

R5 - Max 16host

199.1.1.103 - 199.1.1.119 - SN 255.255.255.240

R6 - Max 8host

199.1.1.120 - 199.1.1.128 - SN 255.255.255.248

For R4 im not ask how many Host & for R1 but since R1 is linked to Router ISP should i give R1 S0/0 a Public Address ?

That subnetting is wrong I am meant to sub net 172.170.0.0/16 to fit 15host on r2 and on r3 7lans on r5 and 5 lans on r6

What is the easiest way to do
