Alteon Application Switch Operating System Application Guide
Server Load Balancing
The default value for the virtual service client NAT capability (Proxy IP Mode) is ingress, so no
special configuration is required on the virtual service in this case. To use egress port-based
proxy IPs:
>> Virtual Server 1 80 http Service # pip/mode
Current pip mode: ingress
Enter new pip mode
[disable|ingress|egress|address|nwclss]: egress
Specific Proxy IP Address for Virtual Service
You can configure a specific proxy IP address (or entire subnet) per virtual service.
When you configure a specific IP subnet as a proxy IP pool for a virtual service, you can also define
whether to select the proxy IP address for each connection in round-robin mode with no persistency,
or to ensure client IP persistency (translate all connections from a certain client IP using the same
proxy IP).
For a virtual service, you can configure an IPv4 and/or an IPv6 proxy IP address (both could be
needed in a mixed IPv4/IPv6 environment).
You can configure up to 1024 IPv4 subnets, and up to 1024 IPv6 addresses per Alteon, as specific
proxy IP addresses or as part of proxy IP network class.
Host Preservation
You can choose to translate only the network prefix portion of the client IP address, and to preserve
the host portion.
For example, if the proxy IP address is set to 20.12.32.0/255.255.255.0, client IP 133.14.15.29 is
translated to 20.12.32.29, client IP 145.11.23.67 is translated to 20.12.32.67, and so on.
This capability requires configuring a proxy IP subnet for the virtual service.
To configure a specific proxy IP address for a virtual service
1. Configure real servers, groups, and a virtual service.
2. Configure a proxy IP address for the virtual service.
a. Configure a single proxy IP address:
>> Virtual Server 1 80 http Service # pip/mode
Current pip mode: ingress
Enter new pip mode
[disable|ingress|egress|address|nwclss]: address
>> Proxy IP# addr
Current PIP addresses:
v4 none
v6 none
persist disable
Enter new IPv4 PIP address or none []: 2.2.2.35
Enter new IPv4 PIP mask [255.255.255.255]:
192
(Select egress port or VLAN-based
proxy IP mode)
(Select PIP Mode Address/Subnet)
(Define proxy IP address)
