I have ipsec setup on untangle and on my android phone, for some reason after about 10-15 min it seems to drop the connection. Is there anyways I can keep the connection open longer for uses like 'always on VPN' and such? I also noticed that the ipsec tunnel tab has the options to keep the connection open but I think that's only for site to site right? I just want to keep it from timing out ever 10-15 min on a untangle to android phone setup.
