Hi Guys,
I have got 2 old DM7020S and a 500S.
All these used to work. Now when I try to use any of these on my network they all connect to my server box (VU+Duo).
But they will not connect to any WAN server. They all just come up red.
I have tried various E1 firmware and cams in all boxes but just cannot get any of them to work. I have even done the ethernet capacitor mod fix
on the DM7020's.

Maybe someone has had a similar problem. Any help would really be appreciated.

Thanks.
Regards,
Jules.
