Arris SBG8300 as provided does not allow VPN pass-thru.
There is article (link below) that provides direction how to do so. But this requires newer firmware version 01.02.078.04.NCS or later to enable via ALG sub-menu.
My box has earlier firmware 1.01.137.NCS which does not have the ALG menu. Thus I cannot enable VPN.
Arrris support says contact my ISP (Spectrum) to push new firmware.
BUT: Spectrum doesn’t have the new firmware; they say that Arris has not provided any updates since the 1.01 version.
SO: caught in nowhere land, cannot use VPN. The link below is helpful ONLY if you have firmware 1.02.078 or later; if you do not, then apparently SOL??
Anyone else having this issue? Any work-around??
Link below that helps if you have proper firmware:
