Never had success with DDNS and central stations (especially those running Sentinel or Immix). The two static IPs idea might work though will need to check with the client if the provider, O2, will do this cheaply Will feed back.

Hi all The scenario is; We have a client with a Vista Smart disk DVR routed to a central station via ADSL (site 1). They have a second site that cannot get ADSL so have it on a 3G dongle into the router which works (site 2) of a fashion. BUT Every time the site 2 unit connects it has a new IP (dynamic address) so the central station cannot identify the site. I have created a permanent VPN between the 2 routers (both DrayTek) on the sites mentioned and can access site 2 from site 1 but I can't work out how to route outbound traffic via the VPN and on to the central station. My ideal solution is a static public IP on a sim (3G or 4G) but where to buy. OR (and why I'm asking) Another solution suggested by this community Hope you can help....

Hi, agree with aisecur. 100% derwent and I may have a selection kicking about but unsure of the precise models, i'll come back to you.

Predominantly in CCTV since 1987 after a previous life as an electrician/instrumentation engineer. Picked up access control along the way and now into very special projects using rad-tolerant cameras, thermal and ATEX. Say hello
