Hello @MartinLangmaid ,
Your article is a very interesting read and very timely for a project our team is currently involved with due to roll out in just over three weeks. I think “Asymmetrically Routed VPN” as a name fits OK.
We have a interesting location here in Australia where as a team are together rolling out to seven locations a large scale industrial agriculture network (for use by both operations, local staff and remote staff) using multiple satellite services (they already have fourteen services, 4 at site one, 3 at site two, 2 at sites three & four, 1 at the remaining sites of five, six & seven)), the nearest town to any of these seven sites is about 80 km (about 50 miles), with the furthest being 120 km (about 75 miles), there is a possibility of a low frequency HF radio option to get small amounts of packet radio back to the nearest major centre, would this work with the solution in your article?
There is an existing analogue telephone network via some old carrier radio links, though almost all of the carriers in Australia have abandoned dial-up and ISDN which would have been another option, at these locations there is no ISDN, dial-up could be used if we could still find the right partner and location to dial back to. Did I forget to mention the nearest mobile phone station is not an option without a 100 meter plus high mast ?
We would also like to hear from anyone else open to sharing there wisdom and experience and solution here.
Appreciate your assistance,
