First problem is you can not run an dhcp server for your ISP IP
address.
You should be using dhclient on the NIC interface name facing the
public ISP.
ifconfig_rl0="DHCP" # adsl 0
ifconfig_rl1="DHCP" # adsl 1
ifconfig_rl2="DHCP" # adsl 2
This will cover both dynamic and static IP address assigned by your
ISP to you.
The dhcp server on your gateway box should only contain lease info
for the 3 separate legs of your local LAN (192.168.2. 192.168.3.
192.168.4.).
The simplest way to utilize your 3 adsl connections to your ISP is
to allocate one adsl line per local LAN leg.
nat on $adsl0 from $net1:network to any -> ($adsl0)
nat on $adsl1 from $net2:network to any -> ($adsl1)
nat on $adsl2 from $net3:network to any -> ($adsl2)

Greetings,
I'm having bad times trying to set up a kind of advance router with
FreeBSD 6.1.
The system has 6 Network interfaces, 3 for adsl connections (one nic
for each adsl, same ISP) and other 3 for 3 sub networks class C
(192.168.2. 192.168.3. 192.168.4.)
The server is running Squid and is using only the first adsl
connection and thats ok.
I'm doing NAT with PF but the problem is when i try to nat each sub
network by each adsl connection.
nat on $adsl1 from $net1:network to any -> ($adsl1)
nat on $adsl2 from $net2:network to any -> ($adsl3)
nat on $adsl3 from $net3:network to any -> ($adsl3)
but that doesn't' work, right now I'm NATing all sub networks with
adsl1 only and the others 2 adsl are being waste without use.
these adsl use dhcp to get the IP and here is the info
lease {
interface "adsl1";
fixed-address 201.242.241.180;
option subnet-mask 255.255.248.0;
option routers 201.242.240.1;
option domain-name-servers 200.44.32.13,200.44.32.12;
option domain-name "cantv.net";
option broadcast-address 201.242.247.255;
option dhcp-lease-time 11637;
option dhcp-message-type 5;
option dhcp-server-identifier 200.109.126.37;
renew 3 2006/6/14 16:56:54;
rebind 3 2006/6/14 18:09:37;
expire 3 2006/6/14 18:33:53;
}
lease {
interface "adsl2";
fixed-address 201.242.241.149;
option subnet-mask 255.255.248.0;
option routers 201.242.240.1;
option domain-name-servers 200.44.32.13,200.44.32.12;
option domain-name "cantv.net";
option broadcast-address 201.242.247.255;
option dhcp-lease-time 19174;
option dhcp-message-type 5;
option dhcp-server-identifier 200.109.126.37;
renew 3 2006/6/14 17:59:58;
rebind 3 2006/6/14 19:59:47;
expire 3 2006/6/14 20:39:45;
}
lease {
interface "adsl3";
fixed-address 201.242.241.150;
option subnet-mask 255.255.248.0;
option routers 201.242.240.1;
option domain-name-servers 200.44.32.13,200.44.32.12;
option domain-name "cantv.net";
option broadcast-address 201.242.247.255;
option dhcp-lease-time 11627;
option dhcp-message-type 5;
option dhcp-server-identifier 200.109.126.37;
renew 3 2006/6/14 16:57:13;
rebind 3 2006/6/14 18:09:52;
expire 3 2006/6/14 18:34:07;
}
Note that the 3 adsl interfaces have the same gateway, but now, how
i
can load balance or at least define the usage of each adsl
connection
for my sub networks? I tried using route but the routing table
always
use the interface of the first adsl.
Any ideas, suggestion?
thanks in advance.
