Thanks Andrew. Will follow up on those ideas too, thanks.<div><br></div><div>However, I have another idea, a bit left field, but it may just do the trick...</div><div><br></div><div>Does anyone know whether 4G modems (and smart phones, for that matter) are assigned a publicly-routable IP address or are they typically NAT'd behind a small number of IP addresses of the mobile service provider's servers? I can't imagine billions(?) of mobile phones all having unique publicly-routable IP addresses (on top of all the servers and so on, around the world).</div><div><br></div><div>If they're NAT'd, then maybe a pre-paid 4G USB modem dongle would be the way to go for low MB critical online work, eg. fetching package lists, logging in to ASIC, ATO, webmail, our utilities, etc. Should block all scanners on the net that are looking for routers to exploit, by virtue of sitting behind the Svc providers routers. (...and then use an unsecured computer and ADSL router pair for general web browsing, content streaming, etc).</div><div><br></div><div>Does anyone know if this would work?</div><div><br></div><div>(Of course, if a 4G dongle is not NAT'd then I don't really gain anything).</div><div><br></div><div><br></div><div><br></div><div><br>On Wednesday, 21 October 2015, Andrew Cooks <<a href="mailto:acooks@gmail.com">acooks@gmail.com</a>> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div class="gmail_extra"><div class="gmail_quote">On Wed, Oct 21, 2015 at 9:43 AM, Dirk <span dir="ltr"><<a href="javascript:_e(%7B%7D,'cvml','justanothergreenguy@gmail.com');" target="_blank">justanothergreenguy@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><div><br></div><div>Cheers for that Pavel.

I have a TP-Link TD-8817 modem in bridge mode, connected to a fit-pc (<a href="http://www.fit-pc.com/web/solutions/multilan/" target="_blank">http://www.fit-pc.com/web/solutions/multilan/</a>) running IPFire (<a href="http://www.ipfire.org/" target="_blank">http://www.ipfire.org/</a>). IPFire tells me I can trust my DNS. IPFire packages are kept up to date. The modem could conceivably modify the PPPoE frames in transit, except that it's a dirt cheap consumer product with little functionality that could be exploitable and it's unlikely to have enough processing power to do that kind of thing.</div><div><br></div><div>There is nowhere safe, only acceptable risks.</div><div><br></div><div>a.</div><div><br></div></div></div></div>
