Configuring Load Sharing Nat Server - H3C MSR 2600 Configuration Manual

Step
3. Configure one or
more common
NAT Server
mappings.

Configuring load sharing NAT Server

You can add multiple internal servers to an internal server group so that these servers provide the same
service to external hosts. The NAT device chooses one internal server as the destination server based on
the weight and number of connections of the servers when an external user sends application requests to
the external address of the internal server group.
To configure load sharing NAT Server:
Step
1. Enter system view.
2. Configure a NAT Server
group and enter its view.
3. Add an internal server
into the group.
4. Enter interface view.
Command
•
A single global address with a single or no global port:
nat server protocol pro-type global { global-address |
current-interface | interface interface-type
interface-number } [ global-port ] [ vpn-instance
global-name ] inside local-address [ local-port ]
[ vpn-instance local-name ] [ acl acl-number ]
•
A single global address with consecutive global ports:
nat server protocol pro-type global { global-address |
current-interface | interface interface-type
interface-number } global-port1 global-port2
[ vpn-instance global-name ] inside { { local-address |
local-address1 local-address2 } local-port |
local-address local-port1 local-port2 } [ vpn-instance
local-name ] [ acl acl-number ]
•
Consecutive global addresses with a single or no global
port:
nat server protocol pro-type global global-address1
global-address2 [ global-port ] [ vpn-instance
global-name ] inside { local-address | local-address1
local-address2 } [ local-port ] [ vpn-instance local-name ]
[ acl acl-number ]
•
Consecutive global addresses with a single global port:
