Network conflict problems in Iran

lenahs

Hi,

I'm in Iran and I managed to load up OpenVPN. I originally purchased PIA - but have been having connectivity issues the last few weeks and am now trying OpenVPN.

I'm a novice and not sure about VPN networks etc.

I can load up and connect with OpenVPN - but when I do connect - it shuts down my internet connection. From a lot of reading online I am guessing I am experiencing a network conflict between the TAP-win32 network connection and my internet connection?

I have tried many things to remedy this while reading stuff online - like trying to change my IP etc but I don't really know what I'm doing.

But I think the issue is an IP conflict perhaps?

This is the setting I have when my internet is working and the TAP-win32 is not connected (USING PIA):-

Windows IP Configuration

Ethernet adapter Local Area Connection 3:

Media State . . . . . . . . . . . : Media disconnected
Connection-specific DNS Suffix . :

Ethernet adapter Local Area Connection 2:

Connection-specific DNS Suffix . : mtnirancell.com
IPv4 Address. . . . . . . . . . . : 2.146.76.3
Subnet Mask . . . . . . . . . . . : 255.255.255.255
Default Gateway . . . . . . . . . : 172.23.133.100

When I did manage to get my PIA working (very very rarely) I noted down the settings:-

Windows IP Configuration

Ethernet adapter Local Area Connection 3:

Connection-specific DNS Suffix . :
Link-local IPv6 Address . . . . . : fe80::fcc6:cfc5:7a22:d69a%24
IPv4 Address. . . . . . . . . . . : 10.176.20.6
Subnet Mask . . . . . . . . . . . : 255.255.255.252
Default Gateway . . . . . . . . . :

Ethernet adapter Local Area Connection 2:

Connection-specific DNS Suffix . : mtnirancell.com
IPv4 Address. . . . . . . . . . . : 2.146.76.3
Subnet Mask . . . . . . . . . . . : 255.255.255.255
Default Gateway . . . . . . . . . : 172.23.133.100

- The Local connection 3 is the TAP-win32 network adapter

When I have connected using OpenVPN and my internet stops working - this is the setting:-

Windows IP Configuration

Ethernet adapter Local Area Connection 2:

Connection-specific DNS Suffix . :
Link-local IPv6 Address . . . . . : fe80::fcc6:cfc5:7a22:d69a%24
IPv4 Address. . . . . . . . . . . : 10.113.1.6
Subnet Mask . . . . . . . . . . . : 255.255.255.252
Default Gateway . . . . . . . . . :

Ethernet adapter WiMax:

Connection-specific DNS Suffix . : mtnirancell.com
IPv4 Address. . . . . . . . . . . : 2.146.85.72
Subnet Mask . . . . . . . . . . . : 255.255.255.255
Default Gateway . . . . . . . . . : 172.23.133.100

I don't know if this is the place to post and if any of this is useful - but I'm desperate to try and get this working. I thought originally it might be something to do with the Iran government blocking the VPN - but given it connects okay - it just ceases my internet connection up - this is why I am guessing I need to perhaps change some setting somewhere??? As soon as I disconnect from OpenVPN my internet works straight away without me doing anything.

Any help is greatly appreciated
🙂

oh - and this is the config log of when I can connect to OpenVPN

It would be I guess who I pay for the internet service - MTN Iran Cell - who are a major provider for both mobile and internet.

This is what I can get off the internet device - probably doesn't mean much but I'll paste it here:-

thanks for the heads up...

I didn't need to contact my provider as I've resolved the problem.

Thanks ! 🙂
