Hi,You will need to create active active vpn gateway and connect your on-premises as mentioned in this doc : https://learn.microsoft.com/en-us/azure/vpn-gateway/vpn-gateway-highlyavailable#dual-redundancy-active-active-vpn-gateways-for-both-azure-and-on-premises-networks
Azure virtual network gateway
Hi there,
I have my on-premises firewall with 2 WAN ports
WAN port 1 connect to the internet via Vodafone
WAN port 2 connect to the internet via Comviq
On Azure I build my Azure Virtual Network Gateway.
How should I configure Azure side and on-premises for such scenario?
Should I setup two local network gateway on azure and two connections from my on-premises?
Thanks

I understand that you would like to know how the best methods to establish multiple connections between Azure VPN and OnPrem.
I see @msrini-MSFT has shared the relevant document.
This is highlighted under Highly Available cross-premises along with the requirements
Adding to the above, you can deploy your VPN gateway in either Active-Passive or Active-Active Mode. Both the scenarios should work as expected.
However, for high availability, it is recommended to use Active-Active set up.
Your observation is correct.
You have to create two LNGs each with the IP of different ISPs. Also, BGP is required for this configuration.
Thanks,
Kapil
