Hi,
I have to setup MS teams direct routing & for that i will have to create inbound NAT rule on External LB for lot of ports.
Everything is in Azure. I know we have limitation to add max 300rules per NIC & also cannot add range of ports.
Flow:-
internet --> Azure external LB --> checkpoint Firewall --> SBC server
do we have any other solution for this.. I don't need to use F5 & other LB specifically.
here i see one document for MS teams.

2021-07-04T11:30:46.883+00:00 the request came to open 10000 ports to SBC ... but here i am quite surprised, as the article is saying there are range of ports in the source we can use & destination will be 5061?

You can absolutely add a range of ports on an NSG. I could not find any info about the port ranges needed on that link for teams, can you clarify this at all?
Hi Kumar,
I have the same requirment to host sbc in Azure behind a CP FW.
I think we can use the VIP of the FW instead of the NLB, which is limited in number of ports to forward.
I would appreciate if you may share with me your finding on that topic.
Thank you
