Hi,
 
How do you interpret the following question?
 
Configure an inbound access list 103 on R3's loopback 0 that satisfies the
below mentioned criteria.
 
1. TFTP, SMTP, and WWW traffic are permitted both ways.
2. ICMP ping traffic is permitted from everywhere.
3. All other traffic is implicitly denied.
 
 
My answer is....It seems that something is wrong with it. What is the
question trying to explore by telling "both ways" and "everywhere"
 
 
access-list 103 permit icmp any any echo
access-list 103 permit icmp any any echo-reply
access-list 103 permit udp any any eq tftp
access-list 103 permit tcp any any eq smtp
access-list 103 permit tcp any any eq www
 
 
Any suggestion will be appreciated.
 
Thanks,
 
Noble
