Static IP Confusion

[ARTYCHOKEUK]

I want to create a VPN linked triangle of 3 remote locations as follows:

1. My home office with Netgear FVL328 Hi Speed

2. My office with Netgear FVS328 - all outbound traffic routed through 1.

3. My son's home office with Netgear FVS318

A US site hosts the website and mail servers. We own our .co.uk domain name and others.

1 and 3 should connect with 2 as well as each other and the WAN

The hosting company offers static IP but I'm rather lost. Is this only for the website ?

I think I can configure the routers for VPN but as 1's ISP can't offer DDNS I'm not sure what to do. It seems I need a static IP to create the Gateways. I certainly don't want to surrender bought domain names to DDNS services. Any suggestions please ?

Treat me gently please.... I'm at the boundaries of my knowledge here. :-/

Does your network look like this?

(Updated, with a direct link from 3. to WAN)

Hi Simon

Yes, but add a direct link in addition for 3 to go direct to the WAN. Thanks

I am new here, and this is one of my first posts I am posting answers to.
So I am having difficulties figuring out what you are asking for. I am sure others would be of much more help, but could you specify your problem a bit easier?

Hope I can help

I (think) I have configured the vpn tunnel settings on the routers but my primary question is "where do I need to ensure static IP addresses"?

I recognise that the "endpoints" of the tunnels need to be set but have these challenges to resolve:

a) The ISP for location 1. is unable to offer static IP but seems to offer a centralised IP of some kind - if this is no good, how to work around this ?

b) the US based website and mail servers can provide static IP - this won't help though will it ?

c) is static IP needed also at locations 2. and 3. ?

Thanks for any help
