I think the most recomended solution is to make a BGP peers with your
two-ISP
Put A single LEAF box running BGP and 3 NICs, one nic facing your
server-farm , and 2 others facing your 2 ISP.
Yes, that would be the ideal way and save me alot of trouble, but I've asked
both ISP's and they won't do it for me on the standard ADSL links. One of
them said they would, but only if I upgrade to their higher link offerings
($500-$600/month). So I'm looking for another solution.
Or .. if you realy realy can't get peer, in this condition i'll prefer
using
dyndns tricks.
In case you want to try dyndns tricks :
1. Give all your server IP address from both IP-block
2. Make a Ping script to ping check some host (on the internet) using
diferent IP-address source for every ping-check
3. If one ping check failed, trigger your dynDNS client to register it self
using diferent IP address.
Note: I never do it yet. Hope fully DynDns client can register using
user-defined ip address.
Using this tricks hopefully your user always "see" single FQDN
Hmmm.. this is interesting. I'll see what dyndns services are offered and if
they allow me to re-register DNS on my own IP's, then that wouldn't be too
difficult to do. However the ping script from an external site may need a
better solution.
Thanks for your ideas/comments Bino.
Michael.
Regards
