 Setting up DNS Proxy
Hey guys, so after setting up the ISP redun, it works great!
now i want to setup our internal email server (OWA feature) to be accessable from either lines if 1 line goes down.
example webmail.emailserver.com -> 1.1.1.1 ISP 1 main line
if the line goes down i want it to point to 2.2.2.2 ISP 2 backup line
In the CP fw toplogy-> isp redun -> DNS Proxy i set it up just like that
webmail.emailserver.com = host name
1.1.1.1 = main isp
2.2.2.2 = backup isp.
with DNS TTL of 15 seconds?
now what is my next step. i have the dns setup with my DNS servers externally so it has an A recond for webmail.emailserver.com 1.1.1.1
do i just place a second A record to point to 2.2.2.2 also? im not a big DNS guru so i need some help. |
