Firewall Config advice needed
Basically the issue is this. We are currently in the process of moving ISP and that means a new range of IP addresses. My concerns over the temporary delay in incomming E-mail as DNS changes kick in. (well not me personally but "certain" people at work get shirty if E-mail isn't received instantly :rolleyes: )
So my I have a slightly hardware specifc question. I have a Netgear FVX538 firewall which usefullly has Dual WAN ports. The downside is that now is not the ideal time to get all experimental with my firewall so I need some advice on how to confgure it.
If I set it up in load-ballancing mode and configure each port for my old and new ISP does the second port remain active for incomming connections? i.e. can I set up firewall rules for port1 with my new mail servers IP address and Port 2 with my mail servers old IP address and stilll receive e-mail on both IP's while I wait for the DNS changes to perculate over the internet?
As I read the instruction manual it say that the load balancing is actually only applied to the outgoing connections but doensn't really mention incomming.
I currently have it set up to only use a single WAN port. I am assuming that the second port is "deactivated". Is this the case? Can I just plug in a connection to the second port and it still be active and thus accept incomming traffic?
Any suggestions would be appreciated.
