I'm trying to setup a vpn connection between my DG834 and a Zywall 25 firewall, with no success so far.
Both boxes are running latest version of respective firmware.
I'm trying to setup an ipSec tunnel between the two gateways. I get the following error:
xx initiating Main Mode xx sending notification INVALID_PAYLOAD_TYPE to :0
Both routers are set to use 3DES/SHA1 but it seems that they don't agree on the handshake.
- did anyone manage to setup such a VPN ? If so would you mind posting the settings used ?
- is there any way to get more detailed logging of the key exchange ?
- is there any other settings past the one available through the web interface ?
Any help / pointer most welcome
