Multiple gateways?
Hello all, Another quick question here.. I have a box with dual gb nics and I was curious if there was a relatively easy way to connect it to two separate gateways. For example, em0 is configured to be 10.223.223.223 with a gateway of 10.223.223.254 and em1 is configured to be 10.224.224.224 with a gateway of 10.224.224.254. TIA Reuben A.

Re: Multiple gateways?
You need to have only one default gateway. But you can use routed to configure other gateways. Note: without a routing daemon all your gateways are default gateways, this will almost certainly cause you problems. On 7/25/06, Reuben A.

Hi there, With ipfw you can do multiple diverts and natds on different ports, choosing which traffic will use wich gateway by source or destiny. xl0 = 192.168.1.2 - gw 192.168.1.1 xl1 = 10.0.0.2- gw 10.0.0.1 ... add divert 8669 ip from any to 192.168.1.2 via xl0 in add divert 8669 ip from 172.16.0.0/16 to any 80 via xl1 out add fwd 192.168.1.1 ip from 192.168.1.2 to any add divert 8668 ip from any to 10.0.0.1 via xl1 in add divert 8668 ip from 172.16.0.0/16 to any via xl1 in ... Suposing your default gateway is 10.0.0.1 and alternative gateway is 192.168.1.1 and your network is 172.16.0.0, with this rules your web requests are going through alterative gateway, and all the rest through default gateway Another way is using pf, where you can even do a round robin use of both gateways, as in http://www.openbsd.org/faq/pf/pools.html.

Multiple gateways
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.

RE: Multiple gateways
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)

Freebsd multiple gateways
*My apologies if this mail has already gone to this list, but I didn't realise you had to subscribe first, im a newbie to mail-lists* I have a problem with having 2 nics and the need for multiple gateways for IP's that are bound to them, heres my prognosis in detail :-# Background Scenario :- I have a server that is running FREEBSD 4.7-STABLE. This server has 2 network cards. Each network card has its own pool of IP's and are on different subnets which are transported by different carriers. Details :- The servers main hostname is admin.mghost.net the IP is 66.250.145.138, the default gateway for this is 66.250.145.137, these ips are on the cogent network, all traffic in/out of the server for the ip 66.250.145.138 should be routed through the gateway 66.250.145.137. These are all on the first network card which is an realtek card. The servers second hostname is test.mghost.net the IP is 69.1.78.8, the default gateway for this is 69.1.78.1, these IP's are on the internap network, all traffic in/out of the server for the ip 69.1.78.8 should be routed through the gateway 69.1.78.1. There are all on the second network card which is an intel thing. The problem :- It appears there is no easy way to add a second default gateway, something I did, which I thought was working, is not. all inbound traffic destined for the IP 69.1.78.8 is going through the correct channels and through teh correct nic, however, outgoing traffic is being routed to the default gateway, through the first NIC, so when people connect to the IP 69.1.78.8, the traffic is being sent through the first NIC and through the gateway 66.250.145.137. The needed solution :- I need something that will allow me to make traffic that is destined for the IP 69.1.78.8 to be routed through the correct NIC and the correct router, not the default gateway, so traffic from 69.1.78.8 back out again, should go via the gateway 69.1.78.1.
