    I reloaded the firmware, restored settings to default and restored settings that I saved and the VPN policy page seems to be working fine now.

    Thanks!

Thanks for the suggestion. I tried your sequence exactly and it still did not allow me to change the encryption. But...this is weird and certainly must be a firmware bug. I was finally able to change the encryption by doing the following:

1) Select VPN Policies and disable the one I created

2) Click Edit

3) Change the Policy type from Auto Policy to Manual Policy and then change it back to Auto Policy. When I did this I noticed that the Manual Policy Parameters got grayed out where before they were not.

4) Change the Encryption type to AES-256 in the Auto Policy Parameters section. When I clicked Apply, it asked me to enter End IP addresses in the Traffic Selection section for both Local and Remote. That I can do!!

5) Now when I click Apply it is all good!!

6) Now I can change the Encryption in the IKE policy to AES-256 and then re-enable the VPN policy

 

This unit is not yet in service or connected to our primary WAN link, so hopefully it will work once it trys to sync the tunnel with our live network. I guess it's possible I got a bad firmware upgrade so I should probably try to reload it.

 

Thanks for the help!

Hi johnjvictor, 

 

I must say that was a weird behavior. Reloading the firmware and resetting it to default should be a good idea. Hopefully, it works fine during production. 

 

Let us know if you have more questions. The community is happy to help! 

 

Thanks,
