    IPAD PPTP WIFI Connectivity Problems

    I was wondering if anyone else has encountered this issue, and have managed to find a work around / fix.

    I use the IPAD1 with OS 4.3.3(8J3) and all works as expected apart from the VPN. I have a VPN setup that uses the PPTP protocol and i can connect fine via a PC running windows 7. with the ipad i am unable to connect to the VPN server over wireless.

    Having googled and read forums -some say its a OS issue, others state its encryption.I have disabled encryption for the VPN, disabled enctyption on the Wireless router but still have the connectivity issue over wireless. even tried various wireless a/b/n setting - However, if i turn on the 3g connectivity it connects to the vpn server perfectly.

    any suggestions will be most helpful.

    thanks

    I'm not sure what wireless ADSL router you have but, on mine - a Linksys, VPN is disabled by default. It's buried quite deep in the Linksys menus so it's easy to overlook. I'm sure you'll have checked this, but just thought I'd mention it......

    Did you check to see if VPN is disabled on your router? In my Linksys, as I mentioned, it's buried quite deeply in the menu structure.

    Thanks for you answer, but like aga2571, I have no problems connecting my pc. It works fine, and ipad connects to vpn, router detects it, and symbol of vpn connection appears on the screen. The problem is that I don't have access to anything.

    OK - but aga2571 can connect over VPN using 3G but can't connect using WiFi via his router. So I suspected that he has VPN disabled in the router. The iPad set-up must be OK as he can connect via 3G.

    Yes, my problem is in fact a bit different.
    When I try to establish a vpn to my network (by 3G or wi-fi) I have the same problem: athetication is ok, login is ok, remote router identifies correctly the user, ipad has vpn sign on screen, but no data flows between private network and ipad. I'm not able to ping machines on my vpn from ipad, and machines on vpn cannot ping ipad, despite correct vpn connection of ipad. When I connect my portable computer to same vpn, by 3G or wi-fi, it works fine. Configuration is the same.
    I deleted vpn configuration some times and created it again, tried all security options, and so on, and nothing works.
    Could somebody help me?
    Thank you.

    I've moved this to the Help section to see if it attracts more attention.

    Dear All,

    Just to put some clarity on things, I am connecting to a Cisco RV042 router (at the office) which has an inbuilt pptp server, as mentioned in my previous post i can connect perfectly from my windows 7 laptop (home pc) using ppt to the RV042 at the office. I can also access the office LAN devices. So, this proves everything on the VPN side of things is setup correctly and works as expected. The Windows 7 Laptop connects via Wireless to the home router.

    So, now if I configure my Ipad on the home WLAN I can connect to the internet and pick up my mail, which proves that the wireless connectivity and internet connectivity is functional and works as expected.

    However, if I configure the PPTP VPN settings on the ipad and try to connect to the office via WIFI - it fails. If I disable the wireless on the IPAD and enable the 3G connectivity, I am able to connect to the office perfectly using the same vpn setting (that did'nt work over wifi) - so..????

    Stuck !!! may be its a OS issue ???

    I was recently confronted with this same problem. It seems that the iOS does not properly send ALL traffic through the VPN when connected. If your local WiFi network and the remote VPN connected network use the same subnet (e.g., 192.168.0.x) then traffic that should be going to the VPN will stay in your local network. Workaround is to change one of the network's subnet.

    I realize this is an old thread, but thought I would post this solution for others who find this forum via a Google search as I did.

    Edit: I realize in re-reading this that two different problems are mentioned. The OP, aga2571 cannot connect to the VPN at all via Wifi. I can't help with that. My solutions is for mbrizida, who can connect but not pass traffic.
