VLAN between RB951G-2HnD and RB260GS ???

I’m trying to setup a trunk between router (RB951G-2HnD) and a switch (RB260GS).
In my design:
router-ether5 <=> trunk <=> switch-port1

Switch setup:



Router setup:

# sep/07/2014 11:30:08 by RouterOS 6.18
# software id = 80AC-XWGX
#
/interface bridge
add l2mtu=1594 name=bridge-local
/interface wireless
set [ find default-name=wlan1 ] l2mtu=2290
/interface ethernet
set [ find default-name=ether1 ] comment=WAN name=ether1-WAN-ADSL
set [ find default-name=ether2 ] comment=LAN name=ether2-master
set [ find default-name=ether3 ] master-port=ether2-master
set [ find default-name=ether4 ] master-port=ether2-master
set [ find default-name=ether5 ] name=ether5-trunk
/ip neighbor discovery
set ether1-WAN-ADSL comment=WAN
set ether2-master comment=LAN
/interface vlan
add interface=ether5-trunk l2mtu=1594 name=vlan1 vlan-id=1
add interface=ether5-trunk l2mtu=1594 name=vlan10 vlan-id=10
add interface=ether5-trunk l2mtu=1594 name=vlan20 vlan-id=20
/ip pool
add name=dhcp_pool1 ranges=192.168.1.10-192.168.1.254
/ip dhcp-server
add address-pool=dhcp_pool1 disabled=no interface=bridge-local name=dhcp1
/interface bridge port
add bridge=bridge-local interface=ether2-master
add bridge=bridge-local interface=vlan1
add bridge=bridge-local interface=vlan20
/ip address
add address=192.168.1.1/24 interface=ether2-master network=192.168.1.0
/ip dhcp-client
add default-route-distance=0 dhcp-options=hostname,clientid disabled=no \
    interface=ether1-WAN-ADSL
/ip dhcp-server network
add address=192.168.1.0/24 gateway=192.168.1.1
/ip firewall nat
add action=masquerade chain=srcnat
/ip upnp
set allow-disable-external-interface=no
/system leds
set 0 interface=wlan1
/system ntp client
set enabled=yes primary-ntp=82.197.0.130

Pretty basic setup, but something doesn’t work tough.
The clients on VLAN20 can set successfully the DHCP address, but cannot see the internet, nor other devices outside of VLAN20.

What Im missing?

Accidently found that, disabling VLAN1 on the Router side makes the thing: Switch clients on VLAN20 started to work normally…
