Firstly I apologise if this has been mentioned in the forums before - I looked but couldn't find anything.
We have a Vigor router at work - with a USB port which can take a 3G Vodem/Data card type connection in case the broadband fails. I understand that when the 3G kicks into life, we will be ok browsing the internet - but I really want it to receive emails from our ISP into the Exchange Server.
But the ISP needs a fixed IP to push the emails to.
What's the best way to handle this?
1. Have an offsite server pickup the emails and forward them to the 3G connection once we've established what the IP address is? (Requires manual configuration - no 100% auto failover)
2. Or is there someway to fix the IP on a 3G connection? I've heard that Telecom charge about $250 per month for the privilege and Vodafone have quoted $3-4K....although I'm not sure if that's just setup or if its an annual charge etc.
3. Even if I do manage to get a fixed IP address for the 3G, will the ISP (Orcon) be able to automatically swap to a different IP - or will that need to be manually configured when it happens?
We expect to use it 3-4 times a year - but emails are pretty important to us so we are willing to spend some money - was just trying to see what options are out there without paying silly money.
Any feedback welcome!
