Re: [FW-1] How to connecto to 2 ISP's?



I checked Radware's website but they don't give much of an explanation on how it is supposed to function.  Anyone know how inbound traffic multi-homed is supposed to work without BGP?  A white paper would be great.

There's at least two ways to use two different ISP's.
One method is to use BGP to handle routing issues.  Hopefully some BGP experts can jump in and advise you on the ins and outs of that solution.

Another method is to use a device like Radware's LinkProof (www.radware.com).  You connect the lan side of the routers from your two ISPs to the 'incoming" side of the LinkProof.  The 'outgoing' side of the LinkProof connects to the external interface of your FireWall-1.  All the NAT and DNS issues are handled by the LinkProof.  Turn NAT off on FW-1 and use private addressing on the external interface.  The net effect of having two ISP's coming in to the LinkProof is that you get load balancing and redundancy.
There are other similar products to RadWare's LinkProof.  Fatpipe has something like this.

Howdy,

for a moment we taught our ISP went bankrupt last week. Fortunately this
turned out not to be the case, however this kind of woke up upper management :-).
So I'm now investigating how to use 2 ISP's for our Internet connection.
Anybody any experience with this? Any links to usefull info?
Is this something that should be solved on the firewall level or will some
router magic do the trick?

Thanks in advance,

Nico
