Hello!
My provider is deliver to me internet and IPTV STB Q11. I remove his router device and I put routerBoard 951.
I have 2 PC and 2 TV + 2 STB Q11.
Now my network work like this ->
PORT1(WAN) and PORT2(to switch-> to TV boxs STB Q11) in BRIDGE 1
PORT3,4,5,wlan,eoiptunel in BRIDGE 2 (with DHCP) to my Computers

I want my network to seems and work:
PORT1(WAN) and PORT2,3,4,5,wlan,eoiptunel in BRIDGE 1(with DHCP) and on PORT 2,3 to use for my IPTV

Is it posible?

Thanks!

It really depends on how your ISP delivers IPTV over WAN and thus how STB expects it to be delivered.

OK, I change the plan
IP-TV site -> Bridge1(ether1(wan),ether2(ip-tv box for other TV), IP-TV-tunnel(EOIP)), Bridge2(ether3,4,5,wlan)
Other site ->Bridge1(pppoe1(wan),ether2,3,4,wlan) , Bridge2(ether5,IP-TV-tunnel(EOIP))
I think the connection is success, the traffic on IP-TV-tunnel is 10Mbps constantly. The STB loading to 36% and stop with error "Failed to synchronize time"...
And now I am stack!

I'd expect the STB to need access to both the IPTV VLAN and the internet VLAN, have you provided both on the port to which you connect the STB?
