Hello,

 

you either need to specify a local dns entry for smtp.mail.com on the Cisco router, or specify a DNS server that can resolve the DNS name:

 

ip domain-lookup
ip name-server x.x.x.x
or
ip host smtp.mail.com 10.10.10.1

!

ip access-list extended VLAN10_ACL
permit tcp host 10.1.20.5 host smtp.mail.com eq 587

i was told fqdn is not supported on 4500 is it correct ?
