Question regarding RED setup- newbee

Hi,

ASTAR0220 v8.306 ===HQ
type of internet connection= DSL 4.5MBPS

RED10 rev.1 =======Branch
type of internet connection= DSL 6Mbps


Successfully connected RED to HQ. i can ping my gateway from branch to HQ and vice versa. My DHCP is from ASG220.

But, when i browse my internet using RED, its so slow and sometimes i can not even browse the internet.

I also experienced pinging other computer on HQ but i cant ping. the only thing i can ping is the gateway.

Is there something i missed in my configuration?

By the way my configuration in unified.

Hoping for quick response.

Thanks


God Bless
