I have a Balance 20 running 5.4.7. I got it years ago for failover because my ISP at the time was unreliable. This router has been rock-solid and wonderful.
Now let’s switch gears.
I have not been able to connect to the computers at my parents’ house via Mac screen sharing since they became AT&T U-verse® customers. The all-singing all-dancing router/telephone/television CPE that AT&T installed doesn’t support UPnP or NAT-PMP and its router cannot be placed into a dumb bridge mode. There are super-complicated and obviously fragile quasi-official instructions online about how to make this box mostly kinda-sorta work as if it were in bridge mode, but I’m not going there. Also please note there are multiple computers at their house, so configuring IP reservations and port mapping isn’t gonna fly either.
Today, I checked the the Peplink web site just to see what if any wonderful things might have transpired since I last visited, and, happily, some have. Apparently, there’s a major new firmware upgrade (6.x) which not only supports easy site-to-site VPN configuration but may even (if I’m reading correctly, I hope I hope) deal with NAT issues as well. And apparently it’ll run on my Balance 20. Wow.
I could totally see buying another Balance 20 (and upgrading the firmware on my existing one) and plunking the new 20 down at my parents’ house behind AT&T’s crippled router if I could set up a site-to-site VPN that way and thus be able to make screen sharing work via VPN. The new Balance 20 would be scandalously underutilized and mostly redundant given its position behind the AT&T box, but if all it does is solve the screen sharing problem for me it will be worth it. As a bonus, it would be cool to have a site-to-site VPN. (Why, yes, I am a geek. How could you tell?)
Has anybody done anything like this before, with specific regard to one of the routers being stuck behind another like this?
Any ideas for how to solve this screen sharing problem another way?
