I build site-to-site-vpn: Server on the cloud with static ip and three sites "home", "office", "city office". All sites are separate and individual, only connection via vpn.
System work properly. Site1 private ip is 10.15.0.0/22, site2 10.16.0.0/22 and site3 10.17.0.0. VPN ip are 10.8.0.15, 16, 17, logically.
Eg. "ping 10.15.0.1" answer from all sites, it is router. And 10.16.0.1, 10.17.0.1. Also printer 10.15.0.7 answer, .4 cctv etc etc. I can use printers over vpn.
BUT. One not work: QNAP Nas. It is 10.15.0.10. Of course I can use it from network 10.15.0.0/22. But this 10.15.0.10 is not available from other sites: I cannot ping, I cannot use webadminpanel, smb not work etc etc.
So, any idea what I must do? Any special router rules? Any special vpn rules? All other network work automatically when build site-to-site-vpn. But this NAS not. Maybe it need any special vpn rules?
