SRX5308 vpn for iphone, laptop
I am not sure this is the right board, but I didn't see another board that was closer. I have an SEX5308 at my office, and an older FV2318g (??) at my home. Both are connected to Xfinity cable modems that are set to "bridge mode". The 2 routers are connected through an IPsec VPN tunnel, which works fine under normal circumstances. The office router (5308) also used to work as a PPTP VPN server for people who were on the road and needed to connect to the network. Everything was fine. Then apple decided in there unfathomable wisdom the PPTP was not secure enough and stopped supporting it. Not only are the iphones and tablets not able to connect anymore, but neither is it possible to tehter a laptop to the iphone and connect, as Apple also stopped the passthrough of PPTP. So, now I am scrambling to get people to connect again. The first thing I tried was to set up a separate IPSec channel for devices (by going through the mode configuration, setting up an Ike policy and user accounts. That works (at least for the iphones), but only for a few hours. After that it stops working, and it breaks the VPN tunnel with the other modem, and the srx5308 has to be rebooted. I don't know what the problem is, but obviously that is not a solution. Then I tried to use L2TP. I set that up, which is essentially just the DHCP part and the definition of handshake protocols. Then, when I try to set that up on my iPhone, I get a message that L2TP requires a "secret" (just like IPsec), but there is no way to enter one in the srx5308. So, no connection either. So, how do I get this to work? How do I keep my VPN tunnel between the 2 netgear boxes humming, and also allow iphones and laptopd to connect?
