Providing Ftp Service From An Ipv4 Network To The Ipv6 Internet - HP FlexNetwork MSR2003 Configuration Manual

Providing FTP service from an IPv4 network to the IPv6
Internet
Network requirements
As shown in
The Internet migrates to IPv6.
To allow the IPv4 FTP server to provide FTP services to IPv6 hosts, configure the following AFT
policies on the router:
•
Configure an IPv4-to-IPv6 source address static mapping for the IPv4 FTP server. The router
uses the mapping to translate the destination IPv6 address of IPv6-initiated addresses to the
IPv4 address.
•
Configure an IPv6-to-IPv4 source address dynamic translation policy. The router translates
source IPv6 addresses of IPv6-initiated packets to source IPv4 addresses 30.1.1.1 and
30.1.1.2.

Configuration procedure
# Specify IP addresses for the interfaces on the router. (Details not shown.)
# Map source IPv4 address 20.1.1.1 to source IPv6 address 2012::1.
<Router> system-view
[Router] aft v4tov6 source 20.1.1.1 2012::1
# Configure address group 0, and add the address range from 30.1.1.1 to 30.1.1.2 to the group.
[Router] aft address-group 0

# Configure IPv6 ACL 2000 to permit all IPv6 packets to pass through.
[Router] acl ipv6 basic 2000

# Configure the router to translate source addresses of IPv6 packets permitted by IPv6 ACL 2000 to
IPv4 addresses in address group 0.

# Enable AFT on GigabitEthernet 2/0/1, which is connected to the IPv6 Internet.
