Configure 2 gateways on a freebsd box for 2 interfaces
Hello all, I have a small question. I have two interface in two vlans. The first interface 192.168.0.1 255.255.255.0 The second interface: 10.228.44.1 255.255.255.0 The gateway for the first interface must be 192.168.0.254 and the second interface must be 10.228.44.254 How can I configure them? In rc.conf we have just defaultrouter but we can't specify the interface.

In response to The Noob [EMAIL PROTECTED]: Hello all, I have a small question. I have two interface in two vlans.

In rc.conf we have just defaultrouter but we can't specify the interface. I'm curious as to why you would want to do this, since that will affect the answer. If those interfaces lead to different networks, then you should add static routes as appropriate. If they are alternate routes, then you should probably run something like RIP to automatically update the routing table. -- Bill Moran http://www.potentialtech.com ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

In rc.conf we have just defaultrouter but we can't specify the interface. I'm guessing you want the gateway to be chosen based on the source address, correct? The kernel does not support routing based on the source address. I use ipfw and fwd rules to achieve this: ipfw add fwd 10.228.44.254 ip from 10.22.44.1 to not 10.22.44.0/24 Then you can leave the default_gateway as 192.168.0.254. You might need IPFIREWALL_FORWARD in your kernel config.

You should be able to use the route command. On Sep 10, 2008, at 1:05 PM, The Noob wrote: Hello all, I have a small question. I have two interface in two vlans.

You will need a static route to pass traffic from interface/subnet to the other. -Derek -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: Configure 2 gateways on a freebsd box for 2 interfaces
Hi, The first interface 192.168.0.1 255.255.255.0 The second interface: 10.228.44.1 255.255.255.0 The gateway for the first interface must be 192.168.0.254 and the second interface must be 10.228.44.254 How can I configure them? In rc.conf we have just defaultrouter but we can't specify the interface. There is no way to specify an interface with the default route. If your default route is set to 192.168.0.254, then it will use the first interface, if the default route is set to 10.228.44.1 it will use the second interface. Now you need to explain why you need to default route. That is more routing issue than FreeBSD issue. In the routing table, you set a list of destination networks and the interface to use to access them. The default route is used to reach all the destinationsthat are not listed else where in the routing table. Your routing table will contain the default information: - to reach network 192.168.0.0/255.255.255.0 you go through the first interface; no need for default route; - to reach the network 10.228.44.0/255.255.255.0 you go through the second interface; no need for default route; - to reach the locakhost you go through interface lo0; no need for default route; You can use the route command to add more (many more) entries into your routing table, and use the default route for everything else. If your host is connected to two Internet sources (two ISPs for example) and you want to add all the best routes for reaching ISP 1 and its clients through the first interface; and all the best routes for reaching ISP 2 and its client through the second interface, then you need to enable some routing protocol. And use the default route for all everything else. To see the routing table on your machine: netstat -r Olivier ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

2 gateways - seperate routes for different ports?
Greetings, I currently have 2 gateway servers that I would like to consolidate. One is a permanent dialup with a static IP - this maintains DNS, routes my SMTP namespace and is relatively secured with IPFW. The other is a cable connection with a dynamic IP running NAT but unsecured because I havent figured out how to configure IPFW with a dynamic IP yet. I want to consolidate these 2 boxes, but I would need to route port 25 and 53 traffic through the dialup connection and everything else through the cable connection? I expect I should be able to do this with IPFW ? No? Any ideas / solutions appreciated. Cheers, Alek.

You could use something like this in your scripts:
/sbin/ifconfig $interface|grep broadcast|awk '{print $2}'
That should take care of the dynamic IP.
