Hello - Thanks Saleh and Javier...

We are working with the vendor to also change the compression they use on the Images so they do not appear so blurry. Stay tuned!

Hello,

Thanks for the interesting post. I am right in saying that your vpn session does not use a certificate? If not how would you go about doing so at the Router's end?

thanks
