Hello everyone, new to experts exchange here and have a question(s) about my recently installed Cisco RV042.

Ive successfully set up and configured the router, but having issues with VPN (im new to setting up vpn tunnels). I have enabled the PPTP server and can connect VPN via Iphone and can remote into network equipment, Yet i cannot access the internet. I work overseas in the middle east where i cannot access some websites - ie: paying bills, netflix, pandora ect.

i have gone through the firewall settings and most of the system configs to see if im missing an easy config setting but no dice.

on a side note, ive signed up with DynDns because my WAN is dynamic, tired to configure it also through the router and keep getting a "Authentication Failed - username and password " error. Ive updated the Firmware and verified user and pass many time with no luck.

any help would be great! thank you!

Normally PPTP will block Internet (I won't use PPTP). I have an RV042 here and Internet is just fine, but I use IPsec.  

I assume that since you can connect with iPhone that your basic internet settings are working. Try disabling PPTP temporarily and see if Internet comes back.

Ive tried disabling the PPTP server, created a test account under the "VPN Client Access" tab in the navigation tree. On the Iphone went to IPsec settings entered in the info of my WAN address, user and pass, and got a "no shared secret was provided". i didn't see a "Secret" field with the account creation.

sorry kind of a noob with it comes to VPN stuff.

Log into the router (Web Management)

1. Status Tab - make sure you have an external IP and that it is connected. You should have some lights on the panel, particularly Internet.
2. On the VPN tab, have you enabled the 3 pass through settings.
3. I looked at my iPhone and do not see how to set it up for IPsec and cannot guide you there.
4. Under Firewall, default should be OK.
5. Under Port Management, nothing should be checked.

I read the PPTP section of the users guide and it suggests PPTP passthrough is enabled by default.

Download the manual and read the sections on PPTP and IPSec thoroughly. IPSec is not trivial and I do not know how to make it work on iPhone. I use IPSec with real computers and it works there.

Do a hardware reset on the RV042 and set it up again and make sure Internet works.

Then try PPTP again, following the manual very closely.

Connecting VPN via PPTP is good yet I cannot access outside my home network- google.com. I've read an re read the manual and it just covers adding users. I've done a hardware reset and upgraded the firmware to the most current version. PPTP pass through is enabled as well as the others by default, I have not made any changes from default. External ip is good as I can browse the interests from my access points. Just trying to figure out why I can't access outside the internal network via VPN through pptp.

I will check with Cisco quick connect at a later time for accessing through the VPN client access, see if that works.

PPTP blocks Internet by default. I checked the settings of my own Router (which I how I posted the stuff above).  You probably should request attention (button in your first post) and ask a Moderator to escalate.  .... Thinkpads_User

I appreciate the help. Before I escalate it I want to make sure I tried everything and it's not some simple overlooked config.

To follow up with everything, somehow i was able to connect VPN via a PPTP tunnel and browse the web. don't really know how i did it but after doing the following it worked.

disabled the PPTP server,
Hard Reboot of Router,
enabled PPTP server,
deleted any profiles saved under the PPTP,
deleted the VPN Profile on the Iphone,
re created the my test profile with user and pass,
re configured VPN profile on Iphone selecting PPTP and credentials, encryption set to auto, send all traffic set to "On",

connected was successful and was able to browse the web during a VPN connection. same experience connecting my MacBook via PPTP VPN. so i think im good now. i will later on figure out connecting via IPsec. will have to iron out some issues with certificates and what not but that will be another thread sometime.

Kudos to Thinkpads_User for the prompt responses!
