      By following the other threads on this forum i've got an IPsec VPN setup on 2.0-RC1 that ALMOST works with an iPad.

      I can connect…. but I can't hit anything on the LAN side.

      My LAN uses 192.168.2.0/24
      The VPN Mobile client uses 192.168.10.0/24

      Here is a snippet of my IPsec log...

      Any ideas why i cant hit anything on my local network?  Has anybody EVER got IPsec (on 2.0RC1) to work with an iOS device?

          I should also point out i have my firewall IPsec rules setup to allow all/any traffic.

          I'm going to call BS on anybody that says they have it working…  ;D

            I'm able to connect to our LAN via iPhone, but when the VPN is activated I can't use the Internet like www.google.com :/

              Can you post your setup?  I'd like to compare mine with yours.

                    After spending a few days on this I've given up  :-[ (for now)..

                    I ended up building a VM using Debian & Openswan to create a L2TP/IPsec vpn server i can use with my iPhone/iPad. I may try again once 2.0 goes final or somebody actually posts a working solution…  but for now i have a working VPN.

                      yeah i think i'm going to opt in for that approach too;

                      did you by chance use a how-to available online that i could reference also to help setting it up on my debian box ?

                            @szop try to make a nat rule for outbound traffic from your ipsec-ip-pool on your wan interface.

                              also working for me with this guide -> http://forum.pfsense.org/index.php/topic,24752.msg130558/topicseen.html#msg130558

                              iphone 4
                              iOS: 4.3.2
                              LAN SUBNET: 192.168.1.0/24

                              i can hit everything at the LAN side. Only the internet (www.google.at as example) is not working, but i think this is a feature for security.. So nobody could go throug your internet connection in your vpn.

                                @pfsenseuser3 do you have a nat rule for outbound traffic from your ipsec-ip-pool on your wan interface? Without this Rule, you IPSec-Client will try to connect to outbound (i.e. internet) with their local ipsec-pool-adresses and doesn't get translated to the wan interfaces address. This means almost every outbound request you send will be dropped by servers configured not to accept traffic from local networks. By adding this Rule, every outbound traffic wlll be translated to your wan interfaces address, this should solve your problem accessing i.e. the internet.

                                    I've tested your hint with outbound NAT which resulted in a complete inaccessibility of LAN and WAN. So i think thats wrong. I can see in the firewall-log only connections to my pfsense, but nothing goes out anymore. So i reviewed my settings regard to IPSEC and found out that at "IPSEC:Mobile clients" disabling the entry "Provide a list of accessible networks to clients" i get connected with LAN accessibility but no WAN.

                                    Reenabling "Provide a list of accessible networks to clients" resulted in full WAN-access via the IPSEC-tunnel.

                                    So no outbound-NAT is necessary. Only the "IPSEC any to any" rule and at WAN-side i have an "ESP to any" rule.

                                    Hope that helps getting a fully working Mobile IPSEC connection.

                                    edit: I have allowed ports 4500 and 500 UDP incoming from WAN, which i forgot to mention. sorry.

                                      @_igor_ are you still able to connect to your lan subnet?

                                      @pfsenseuser3 you should set your outbound nat mode to manual.

                                        @igor when i set "provide accesible networks" i do lose my default route over the tunnel and the client talk directly to the wan since their default route is set to the lan-gateway. this means no traffic to wan at all is routed trough your tunnel. that your client has established a connection and can talk to outbound doesnt mean directly that the traffic is passing your tunnel interface. apart from that i dont believe that theres right and wrong, rather than suitable or not. would you please take a look a you routing table when connected?

                                            @ericab can i help you with somewhat? i believe that theres no tutorial because mobile ipsec works perfectly since months now and everything you need to know to get a basic setup up and running you can find here in this forum.. but anyway, a clean and simple tutorial would decrease the amount of questions asked multiple times. that´s right..
