Reply To: Asus DSL-AC88U VPN issues Hello, I am having some issues with my Asus router and hoping someone can help throw some light on the subject to help resolve it. Background – I have had…

OK, i didn’t want to mess with my other DSL line, as you know, if its not broken leave it alone! [Yes I have 2 separate providers, Sky for SkyQ and general house WiFi and my own separate line which was BT, and is know TalkTalk as detailed above]. So I broke out the ‘Wireshark’ to get my user name/password and connected the Asus to the Sky DSL line, which incidentally after doing the auto setup is also WAN connection type Automatic IP +user/password. And guess what the same happens again, but not every 450 seconds, every 1796 seconds [30 mins], see Sky DSL log below –

So from this I can only conclude they are both trying to prevent continuous VPN connections for some reason or the WAN connection method can only work in this manor preventing a continuous connection, perhaps the latter, as apposed to BT [PPPoE] which does not have this issue.

Its beginning to suggest that my only option with these providers is to have a static IP to prevent the polling [renewal]?
