CCNA Skills Integration Challenge PT Activity 8.6.1 - Task 3



Task 3: Configure Static and Dynamic NAT on HQ
Step 1. Configure NAT.
Use the following requirements:
Allow all addresses for the 10.0.0.0/8 address space to be translated. 
XYZ Corporation owns the 209.165.200.240/29 address space. 
The pool, XYZCORP, uses addresses .241 through .245 with a /29 mask. 
The www.xyzcorp.com website at 10.0.1.2 is registered with the public DNS system at IP address 209.165.200.246.
First we must specify new access-list for using NAT:
HQ(config)#ip access-list standard NAT_LIST
HQ(config-std-nacl)#permit 10.0.0.0 0.255.255.255
HQ(config-std-nacl)#exit
Second action is enabling dynamic NAT translation on HQ.
For this action follow the requirements we must create NAT Pool:
HQ(config)#ip nat pool XYZCORP 209.165.200.241 209.165.200.245 net 255.255.255.248
HQ(config)#ip nat inside source list NAT_LIST pool XYZCORP overload
And last action is enabling static NAT:
HQ(config)#ip nat inside source static 10.0.1.2 209.165.200.246
Also we must activate NAT mode on all interfaces include each subinteface on HQ router.
For all interfaces exclude serial 0/1/0 NAT mode must be configured as inside, for example:
HQ(config)#interface serial 0/0/0.41
HQ(config-subif)#ip nat inside
For serial 0/1/0 it must be:
HQ(config)#interface serial 0/1/0
HQ(config-subif)#ip nat outside
After completion your percentage must be 11%

Task 2: Configure PPP with CHAP and PAP Authentication
Step 1. Configure the WAN link from HQ to ISP using PPP encapsulation and CHAP authentication.
The CHAP password is ciscochap.
We open console on HQ again and begin...

HQ>enable 
HQ#conf t
Enter configuration commands, one per line. End with CNTL/Z.
HQ(config)#interface serial 0/1/0
HQ(config-if)#ip address 209.165.201.1 255.255.255.252
HQ(config-if)#no shutdown 
%LINK-5-CHANGED: Interface Serial0/1/0, changed state to up
HQ(config-if)#encapsulation ppp 
HQ(config-if)#ppp authentication chap 
HQ(config-if)#exit
HQ(config)#username ISP password ciscochap 
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/1/0, changed state to up
do ping 209.165.201.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 209.165.201.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 6/8/14 ms
HQ(config)#do copy r s

[OK]

CCNA Skills Integration Challenge PT Activity 8.6.1


     This article aimed at solving CCNA Skills Integration Challenge PT Activity 8.6.1 and exam CCNA, also for basic configuration of network equipment Cisco Systems
First of all we must configure HQ as a hub router. Entering console:
Router>enable 
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname HQ
HQ(config)#interface serial 0/0/0
HQ(config-if)#encapsulation frame-relay 
HQ(config-if)#no shutdown 
%LINK-5-CHANGED: Interface Serial0/0/0, changed state to up
HQ(config-if)#frame-relay lmi-type q933a 
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/0/0, changed state to up
HQ(config-if)#exit
HQ(config)#interface serial 0/0/0.41 point-to-point
%LINK-5-CHANGED: Interface Serial0/0/0.41, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/0/0.41, changed state to up
HQ(config-subif)#ip address 10.255.255.1 255.255.255.252
HQ(config-subif)#frame-relay interface-dlci 41
HQ(config-subif)#exit
HQ(config)#interface serial 0/0/0.42 point-to-point
