Hi,

I've been working through WB Vol1 and have several questions and comments about 
section 2 (IOS Firewall):

1- Task 3 reflexive:
- Solution has an IPv4 ACL entry for port 81; I don't see this in the question
- Solution matches from any when question says from VLAN62

2- Task 5 CBAC: for HTTP port-map, I added an ACL to be more specific; should 
it include pre-NAT or post-NAT addresses or both?
access-list 1 permit 172.41.41.198
access-list 1 permit 172.41.41.199
access-list 1 permit 10.10.11.199
access-list 1 permit 10.10.11.198
ip port-map http port tcp 8080 10080 list 1

3- Task 6 zone-based firewall:
Solution: ip port-map http port tcp 9080 for IPv4 and an ACL for IPv6.
I used a different approach; are my solutions valid or I'm missing something?
For IPv4, I created a user-defined PAM not to match port 80 and 9080: ip 
port-map user-http9080 port tcp 9080
For IPv6, I don't have the option to create a user-defined port-map in IOS 
15.2, I thought of doing a combination of ACL and adding to the system defined 
HTTP port-map. So this config matches both ports 80 and 9080:

ipv6 port-map http port 9080
ipv6 access-list R5_ACL6
  permit ip any host 5::5
class-map type inspect match-all OUT_DMZ_R5-6
   match protocol http
   match access-group name R5_ACL6

I guess the ACL could be changed to permit tcp any host 5::5 eq 9080 in order 
to be more specific.

Thanks,

Patrick
