HI all Experts,
i have question about IP subnet
Microsoft azure vnet to vnet
Site A = address space 10.0.0.0/22 - subnet 10.0.0.0/24 starting ip 10.0.0.4 VPN connect ( Site B )
Site B = address space 10.0.0.0/22 -subnet 10.0.0.0/25 starting ip 10.0.4.4 VPN connect ( Site A + Site C ) Multi-site
site C = address space 192.168.0.0/24 - subnet 192.168.0.0/24 (VPN connect (site A)
when these 3 sites connected there is an issue with passing traffic through VPN Tunnel. ( 192.168 can't talk to 10.x.x.x/24 or 10.x.x.x/25
If I removed Multi-site and test just VPN One on One ( site C to site A or Site C to site B ) the tunnel allow passed traffic fine.
there something wrong with subnet mask betwwen corp to azure with Multi-site setup.
many thank you...
