Enable bonding:

:   <select name="BONDING" size="1" onchange="check_network_settings_form();">
    <?=mk_option($var['BONDING'], "no", "No");?>
    <?=mk_option($var['BONDING'], "yes", "Yes");?>
    </select>

    > Bonding is a feature that lets you combine multiple physical Ethernet interfaces into a
    > single *bond* interface named **bond0**.  This lets you connect
    > any or all your ethernet ports to the same switch.

    > At present this feature will bond all present ethernet interfaces.

Bonding mode:

:   <select name="BONDING_MODE" size="1">
    <?=mk_option($var['BONDING_MODE'], "0", "balance-rr (0)");?>
    <?=mk_option($var['BONDING_MODE'], "1", "active-backup (1)");?>
    <?=mk_option($var['BONDING_MODE'], "2", "balance-xor (2)");?>
    <?=mk_option($var['BONDING_MODE'], "3", "broadcast (3)");?>
    <?=mk_option($var['BONDING_MODE'], "4", "802.3ad (4)");?>
    <?=mk_option($var['BONDING_MODE'], "5", "balance-tlb (5)");?>
    <?=mk_option($var['BONDING_MODE'], "6", "balance-alb (6)");?>
    </select>

    > Mode 1 (active-backup) is the recommended default.  Other modes may require switch support.

Setup bridge:

:   <select name="BRIDGING" size="1" onchange="check_network_settings_form();">
    <?=mk_option($var['BRIDGING'], "no", "No");?>
    <?=mk_option($var['BRIDGING'], "yes", "Yes");?>
    </select>

    > Bridging allows you to connect two or more network segments
    > within one logical network.  At present this feature will bridge all
    > present ethernet interfaces.

    > **Caution:** if bonding is also not enabled, do not connect two or more
    > ethernet ports to the same switch unless the switch supports STP
    > (most consumer switches **do not**).
    > Doing so will cause an "ARP broadcast storm" and can bring down your
    > entire network (unplugging all sever ethernet ports except one
    > typically will restore your network).

    > If bonding is also enabled, the bridge will initially consist of
    > just the **bond0** interface.  This is useful if you are setting up a bridge for Xen.

Bridge name:

:   <input type="text" name="BRNAME" maxlength="80" value="<?=$var['BRNAME'];?>">

    > This is the name of the bridge interface.  If left blank, the name of the bridge will be **br0**.
    > If running as a Xen dom0 we recommend setting this to **xenbr0**.

Netmask:

    > If set to 'Yes' the server will use DNS server IP address returned by the local DHCP server.<br>
    > If set to 'No' you may enter your own list.  This is useful in Active Directory configruations where
    > you need to set the first DNS Server entry to the IP address of your AD Domain server.

DNS Server 1:

:   <input type="text" name="DNS_SERVER1" maxlength="80" value="<?=$var['DNS_SERVER1'];?>">

    > This is the primary DNS server to use.  Enter a FQDN or an IP address.
    
    > Note: for *Active Directory* you **must** ensure this is set to the IP address of your
    > AD Domain server.

DNS Server 2:

:   <input type="text" name="DNS_SERVER2" maxlength="80" value="<?=$var['DNS_SERVER2'];?>">

    > This is the DNS server to use if DNS Server 1 is down.

DNS Server 3:

:   <input type="text" name="DNS_SERVER3" maxlength="80" value="<?=$var['DNS_SERVER3'];?>">

    > This is the DNS server to use if DNS Servers 1 and 2 are both down.
