I set up the SE VPN Server in virtual network on Proxmox, where is also other VPS (some -
Create Hub, Local Bridge with virtual interface TAP (manual set address), DHCP. Forwarded ports from external Server Proxmox.
Remote clients connect to services of virtual network (through P2TP/IPsec, SSTP).
VPN network:
Use routing:
VPN Net -> Virtual Net 1: gw
Virtual Net 1 -> VPN Net: gw
This config work fine some years.
Next step, i want to add resources from second remote server, also Proxmox (Server-2),
that would clients can connect to Virtual Net 2 (to VPS) on Server-2 (some other -
On Server-2 set up SE VPN Bridge on Virtual Net 2, create Hub-Bridge, Local Bridge with eth0.
On SE VPN Server/Server-1 create Hub-02 (with user for cascade), second interface eth1 (manual set address), Local Bridge Hub-02/eth1.
On SE VPN Bridge/Server-2 create cascade from Hub-Bridge to Hub-02/SE VPN Server/Server-1.
Cascade connecting - established, - OK.
I was going to make routing similary (through interfaces SE VPN Server/Server-1: tap,eth0,eth1), but issue:
Not ping (Destination Host Unreachable):
From SE VPN Bridge/Server-2 eth0/ to SE VPN Server/Server-1 eth1/ (inside Hub-02, cascade connection), and back.
Wherein, in IP address tables Hubs ip-addresses are present.
I don't understand what's wrong :(
Help, please!

Hello, again!

It work! Enough to replace on VPN Server/Server eth1 with second tap (tap2), i.e. Local Bridge Hub-02/tap2.
Like this:
Layer 3 IP routing without switch.
