Hello Everybody,

I've been trying to establish a VPN IPsec connection to my AVM FritzBox7590. I tried a lot of different settings with no success. Before switching to OpenVPN Sever with a Rasperry 4, I would like to ask the community.

Has anyone succesfully set up a VPN connection to a AVM FritzBox? Preferable with RUT850 R_00.01.04.

Anyone?

Hello,

Please refer to this guide on how to configure IPsec on RUT850: https://wiki.teltonika-networks.com/view/RUT850_VPN#IPsec

Also, could you post screenshots to show us how your configuration pages look like on both FritzBox and RUT850?

Regards.

Hi,

here are my settings.As you can see, there not many settings in FritzBox. I think, the big question is, how to provide user name and password on RUT850. The FritBox currently works fine with an Android mobile, where you can enter user name and Password.

[edit: finally got the screen shots posted smiley]

Hello,

You could send me the screenshots via private message. Also, screenshots must be uploaded using the editor in this forum (press the Image icon while posting anything).

Regards.

Hello,

Does the fritz box have any more configuration variables when configuring IPsec? I suspect the reason why you cannot connect to the RUT device is Phase 1 and Phase 2 parameters mismatch. They must be identical in both VPN ends to establish connection. It may require to change config files for your Fritzbox device. For that, I suggest asking around in Fritzbox forums.

Hi,

I already checked this:

Phase 1:

Encryption algorithm: AES 256
Authentifizierung: SHA1
DH group MODP1024
Lifetime (h) 8 Hours

Phase 2:

Encryption algorithm: AES 256
Hash algorithm: SHA1
PFS group MODP1024
Lifetime (h) 8 Hours

I could suggest then to try changing identifier type to another for example Address (I am not sure if Fritzbox supports IKEv2), then mode and your identifier values could be also switched. Also, in the host and IP address/subnet mask you have entered Fritzbox address, right?

It would be interesting to analyze the logs of RUT850 when you try to connect to fritzbox IPsec. Logread output may identify where is the problem.
