OpenVPN server with TAP interface, client didn't see network

Hello, i’m trying to move configuration from 1.2 to 1.4 and can’t understand why client didn’t see LAN.

show interfaces openvpn vtun94 
 device-type tap
 local-port 9001
 mode server
 persistent-tunnel
 protocol udp
 server {
     client-ip-pool {
         start 10.1.4.240
         stop 10.1.4.245
     }
     push-route 10.1.5.0/24 {
         metric 1
     }
     push-route 10.2.4.0/24 {
         metric 1
     }
     push-route 10.3.4.0/24 {
         metric 1
     }
     subnet 10.1.4.0/24
     topology subnet
 }
 tls {
     ca-certificate DCin
     certificate DCinSrv
     dh-params DCin-DH
 }

show interfaces bridge br94

     interface eth0.94 {
     }
     interface vtun94 {
     }
 }
 priority 0
show interfaces ethernet eth0 vif 94
 description Brn-DCin-94

And with this config client get IP 10.1.4.240, can ping 10.1.4.1, can ping other IPs that should be routed (10.1.5.0/24, 10.2.4.0/24, 10.3.4.0/24), BUT can’t ping IPs in 10.1.4.0/24 LAN.

Why? What’s wrong with it? When i open tcpdump on 10.1.4.251 and starts pinging from OVPN client 10.1.4.240 LAN IP (10.1.4.251), i got:

sudo tcpdump -i eth0.94 -vvv  icmp
tcpdump: listening on eth0.94, link-type EN10MB (Ethernet), capture size 262144 bytes
07:41:09.249736 IP (tos 0x0, ttl 63, id 36782, offset 0, flags [none], proto ICMP (1), length 60)
    10.1.4.240 > 10.1.4.251: ICMP echo request, id 1, seq 648, length 40

and zero reply’s…

sudo arp -a
....
? (10.1.4.240) at <incomplete> on eth0.94
....

sudo cat /run/openvpn/vtun94.conf

ifconfig-pool 10.1.4.2 10.1.4.253 -- WHY?
ifconfig-pool 10.1.4.240 10.1.4.245

On 1.2 VyOS there was:

openvpn-option "--server-bridge 10.1.4.1 255.255.255.0 10.1.4.240 10.1.4.250"
Nov 24 16:02:28 r1-brn openvpn-vtun94[232736]: Options error: --server and --server-bridge cannot be used together

In OpenVPN documentation:

For example, server-bridge 10.8.0.4 255.255.255.0 10.8.0.128 10.8.0.254 expands as follows:

mode server
tls-server

ifconfig-pool 10.8.0.128 10.8.0.254 255.255.255.0
push "route-gateway 10.8.0.4"

VyOS 1.2 exec of OpenVPN:

There is –server-bridge nogw and there is no server 10.1.4.0 255.255.255.0 nopool
