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



Wow,

never thought my little mail would spark such a thread :-).
Thanks for al the replies!

So I have two options: BGP or the Radware box.  The BGP solution seems to be the best one
but also the hardest to setup.

1 question about the Radware solution: for incoming connections to my mail or webservers
the Radware box will use DNS to distribute the load over both links. However DNS queries
get cached all over the Internet for periods of days or weeks if I recall correctly.
So if one of my ISP's goes down this would mean some DNS servers on the Internet
might still be caching ip-addresses from that ISP so on the average half of the traffic
won't be reaching my servers? Correct?
