Unable to setup WAN from CLI

Installing and Using OpenWrt Network and Wireless Configuration
1

Hi,
I am having a bit of problems setting up a new installation.
I am setting on x86_64 (actually a Virtual Machine, it shouldn't matter for my problem but I can provide details if deemed useful) with 3 NICs: LAN, WAN and DMZ.
I changed default address of LAN directly editing /etc/config/network and I'm able to correctly access firewall through ssh.

My current /etc/config/network is:

root@OpenWrt:/# cat /etc/config/network 

config interface 'loopback'
        option device 'lo'
        option proto 'static'
        option ipaddr '127.0.0.1'
        option netmask '255.0.0.0'

config globals 'globals'
        option ula_prefix 'fd6a:f194:a931::/48'

config device
        option name 'br-lan'
        option type 'bridge'
        list ports 'eth0'

config interface 'lan'
        option device 'br-lan'
        option proto 'static'
        option ipaddr '192.168.7.253'
        option netmask '255.255.255.0'
        option ip6assign '60'

config interface 'wan'
        option device 'eth1'
        option proto 'static'
        option ipaddr '192.168.2.353'
        option netmask '255.255.255.0'
        option gateway '192.168.2.1'
        option dns '192.168.2.1'

config interface 'wan6'
        option device 'eth1'
        option proto 'dhcpv6'

All other files are at their default value on latest build (i.e.: no editing).

System does not seem to attempt bringing up eth1/wan (which is needed for Internet access).

My current net status is:

root@OpenWrt:/# ip a

root@OpenWrt:/# ip r

As you see there's no default gateway and no way to access modem/router.

I have a modem/router on 192.168.2.1 with a working (tested) DHCP server (I tried using that but I got no connection, so I tried fixed address with identical results).

Where should I enable eth1?

I was unable to find relevant documentation, any pointer welcome.

Thanks @frolic,
good catch.
I was staring at that file since yesterday and I couldn't see it.

Unfortunately nowI can get an IP address, but it doesn't really seem to work.
I need to cross-check my setup again.
