D A server with a fixed IP address can only be contacted via a dedicated
connection. All that is required for the selection here is the destination IP
address.
D A server uses a protocol that requires a control channel and other chan-
nels for data transfer (e.g. FTP, H.323, PPTP). In establishing the data
channels, servers accept only the same IP address as that used by the
control channel.
U Destination-based channel selection
Destination-based channel selection is handled by an entry in the routing ta-
ble that directly uses one of the bundle connections to reach the destination
instead of using the virtual balancing connection.
U Policy-based routing
Suitable entries can be made in the firewall to select channels according to
the destination port or the source address. These entries are supplemented
with a special routing tag that is used to control the channel selection with the
routing table (’Policy-based routing’ → page 358).
11.8.5 Configuration of load balancing
Note: For the following configurations we assume that the remote devices
are already set up with all necessary access data.
