VXLAN communication problems

[dline]

Hello!

I have problem with PVE 8.1.3 and SDN VXLAN configuration

Today we have task to migrate our infrastructure to another site

We have two networks:
10.16.4.0/24 - in old location
10.15.4.0/24 - in new location

All host-nodes can communicate together, PVECM status is okay (Quorate), SDN status is available
Bridge MTU is 1550, VXLAN MTU is 1500
Ping is okay also from both sides:
ping -M do -s 1522 10.16.4.12
PING 10.16.4.12 (10.16.4.12) 1522(1550) bytes of data.
1530 bytes from 10.16.4.12: icmp_seq=1 ttl=62 time=1.65 ms

From SDN:

auto vps
iface vps
    bridge_ports vxlan_vps
    bridge_stp off
    bridge_fd 0
    mtu 1500
    alias public-vps

auto vxlan_vps
iface vxlan_vps
    vxlan-id 2132
    vxlan_remoteip 10.15.4.1
    vxlan_remoteip 10.16.4.11
    vxlan_remoteip 10.16.4.13
    vxlan_remoteip 10.15.4.14
    vxlan_remoteip 10.16.4.15
    vxlan_remoteip 10.16.4.16
    vxlan_remoteip 10.16.4.19
    vxlan_remoteip 10.16.4.20
    vxlan_remoteip 10.16.4.90
    vxlan_remoteip 10.16.4.91
    vxlan_remoteip 10.16.4.96
    mtu 1500

But VMs from new location didn't receive anything.
For example, DHCP request from VM in new office we can see from tcpdump from old office, but response - is not delivered back to requester.

So, how can we fix this issue? Maybe some additional setting we need to setup on our new location nodes?
