Routed public subnet (/28)


I have received a /28 block from ISP and am trying to assign one of the public IPs to a server directly (not NAT).

Gateway: 203.13.YYY.161
Usable IPs: 203.13.YYY.162 - 203.13.YYY.174
Subnet Mask:

Following the advice from a helpful member on lede-dev, I only needed to:
Modify my lan config to add the public block, as such:

config interface 'loopback'
        option ifname 'lo'
        option proto 'static'
        option ipaddr ''
        option netmask ''

config interface 'lan'
        option type 'bridge'
        option ifname 'eth0.1'
        option proto 'static'
        list ipaddr ''
    --->list ipaddr '203.13.YYY.160/28'
        option ipv6 '0'

config interface 'wan'
        option proto 'static'
    --->option ipaddr '203.13.YYY.162'
    --->option netmask ''
        option gateway '203.13.YYY.161'
        option delegate '0'
        option ifname 'eth1.2'
        option ipv6 '0'
        option dns ''

config switch
        option name 'switch0'
        option reset '1'
        option enable_vlan '1'

config switch_vlan
        option device 'switch0'
        option vlan '1'
        option vid '1'
        option ports '0t 1 2 3 4'

config switch_vlan
        option device 'switch0'
        option vlan '2'
        option ports '5 6t'
        option vid '2'

WAN zone in firewall (disable masquerading for public block):

config zone
        option name 'wan'
        option output 'ACCEPT'
        option masq '1'
    --->option masq_src '!203.13.YYY.160/28'
        option mtu_fix '1'
        option network 'wan'
        option input 'ACCEPT'
        option forward 'ACCEPT'

In addition, I needed to adjust the firewall with this rule so anything coming from WAN is properly forwarded:

config rule
        option name 'public'
        option src 'wan'
        option dest 'lan'
        option dest_ip '203.13.YYY.160/28'
        option proto 'all'
        option target 'ACCEPT'

Now with hosts connected to my LAN, assigning public IPs to them should be simply a matter of statically assigning the desired IP on the server itself, eg:
IP: 203.13.YYY.165
Gateway: 203.13.YYY.162 (LEDE router WAN IP)

But once I assign that, they can't connect or ping anything in LAN or WAN.

So in summary, I have a block, LEDE itself is using .162 for its WAN connection, I wish to assign one of other public IPs I received to hosts in LAN without NAT, how can I do that?

Any help is appreciated.
