Not ping to virtualisation server proxmox

[sergey113]

On the proxmox server (debian 10), he created a virtual machine with a VPN softether server. Created the Hub and the user in it (certificate login), TAP interface.
BridgeCreate MyHub -device:vpn -tap:yes
Assigned IP TAP to an interface.
ifconfig tap_vpn 192.168.50.15
Prescribed routes.
From a remote client over a VPN link, I cannot ping the proxmox server interface. At the same time, all tap and other interfaces inside the virtual machine itself are available. Firewalls are off.
Perhaps these are restrictions
3.6.11 Points to Note when Local Bridging in Linux, FreeBSD, Solaris or Mac OS X
https://www.softether.org/4-docs/1-manu ... Access_VPN
I prescribed a rule that did not have an effect.
iptables -t nat -A POSTROUTING -s '192.168.50.0/24' -o ens18 -j MASQUERADE

How do I set up ping?

To work around the Linux kernel VPN ping limitation you need to double-bridge: brctl addif br0 tap_vpn

(BTW, WTF do you redact private-range IPs?)

do you redact private-range IPs?

does not work (

I make:
----------
ip link add dum0 type dummy
brctl addbr br0
brctl addif br0 dum0 tap_art_simple
ifconfig br0 192.168.100.15 netmask 255.255.255.0 promisc arp up
ip route add 192.168.43.0/24 via 192.168.100.15 dev br0
ip route add 192.168.40.0/24 via 192.168.100.15 dev br0
---------
Interface SE server ens18 have IP 192.168.1.15 he does ping.
Interface proxmox server have IP 192.168.1.10 and and he does not ping

[sergey113]

SE is poorly compatible with Linux and better look towards other VPNs?

I set up a connection in the form of two bridge servers, but this did not help
