Hello again, I added topology subnet and now interface tun0 (Debian, VPN server) looks like:
tun0: flags=4305<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST> mtu 1500
inet 192.168.2.1 netmask 255.255.255.0 destination 192.168.2.1
inet6 fe80::7001:ebe3:6059:ae77 prefixlen 64 scopeid 0x20
unspec 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 txqueuelen 100
But, anyway, situation is the same. Turris see Debian and clients behind Debian, but Debian see just Turris but no clients behind it. How do you think - may be I can build test VM (Debian based also) as a OpenVPN client with the same configuration and same certificates to compare? Seems to me is something wrong with Turris…
P.S. Looks like I forget about config route - will try to configure this section:
config route
option interface 'sample_client’
option target '192.168.1.0’
option netmask '255.255.255.0’
option gateway ‘192.168.2.4’ # VPN IP of the client
Is it correct in my case?
