Guys,

small company I look after wanted to expand efficiency and remote support so we arranged for BT to give them 5 x IPs and a router IP.

There is a Draytek Vigor in place which supports WAN Alias.

I set the router IP address to static and gave it the router address that BT had provided. Let's say that's 10.10.10.50

I then used some of the 5 IPs that were given and set one to the exchange box (10.10.10.45), one to remote services (.46) and one to VPN (.47)

I then altered 123reg DNS to point to the ip 10.10.10.45 and opened up the relevant ports for SMTP, HTTP, HTTPS on the Draytek pointing to the internal server 192.168.2.110 (exchange).

We have internet connection, but nothing seems to work. Pings don't work, etc. It's pretty grim. I'm sure there's something I have forgotten to do or broken....

also, if I ping the external OWA name mail.company.com it still resolves to the old static IP address that was in use before we changed over. 123reg are normally really quick so I'm a little concerned....

In the Draytek router, under WAN Alias, is an option to join NAT IP Pool. It's unticked and I have no idea what this does....although after reading around I don't think I need this as it randomises the ip address publically

The DNS resolution is just a waiting game. Try the tools over at mxtoolbox.com to check everything looks okay.

You can leave 'Join NAT IP Pool' unticked for the additional IPs.

Check under NAT->Address Mapping to make sure the servers are using the correct out going IPs.

Don't forget to get the rDNS updated for the new IPs.
 
Thanks

Thing is I made a change last week for someone else on 123Reg and it literally updated isntantly. This is why I think something isn't right :(

Where do I get the rDNS updated?
 
The update time is going to vary. It'll depend on which DNS servers the device you're using to check is using.

For rDNS you'll need to contact the ISP. You'll need to wait until your current DNS changes have propagated.
