So I subscribed to comcast (my cablem modem internet provider) from my home and put a cisco WRV210 in front of the comcast modem. They gave me 1 static ip address which i'm planning to use to access my camera system. I configure the dmz to translate the address to a local one and go straight to the video server. This allows me to access the static ip in the network. This was setup 2 days ago and I've noticed the connection keeps getting slower and slower until the point where I have to reboot the cisco firewall box. upon further investigation, when i plug my laptop into the comcast router, I receive an IP address of 10.1.10.1 which tells me the router also has dhcp enabled.
Is this supposed to enabled? I hope i don't have to return the cisco box and get something else.

thanks in advance
