Hi @Fuma ,
Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.
I understand that you would like to connect 5000 P2S users simultaneously to Azure VPN.
Kindly correct me if I my understanding is wrong
For 5000 Connections, you must use the appropriate gateway SKU that supports this.
Refer: https://learn.microsoft.com/en-us/azure/vpn-gateway/vpn-gateway-about-vpngateways#gwsku for comparison table
The following SKUs may suit your scenario,
- VpnGw4
- VpnGw5
- VpnGw4AZ
- VpnGw5AZ
With respect to P2S Client configuration address pool, you can use a CIDR of /19 and above.
Also, this should not overlap with any of your other networks
For e.g, 10.5.0.0/19 (in your scenario)
Refer: https://learn.microsoft.com/en-us/azure/vpn-gateway/vpn-gateway-howto-openvpn
Please do let us know should you require more details.
Cheers,
Kapil
