Hi, I am setting up network tunnels for a customer to Umbrella. They need multiple tunnels configured as they need more than the 250Mbps bandwidth one tunnel allows for. They want the tunnels to terminate at the same datacenter and both tunnels will connect to one router onsite. However, it seems that I can't configure it that way without changing the source port of at least one tunnel from 4500 to something like 4501. This way both tunnels can be up at the same time.
Can I create multiple IPSEC Tunnels for CDFW? – Cisco Umbrella
However, I can't seem to determine how to do the configuration to change the source port. The customer has in place DMVPN tunnels to their other branches. From what I found, I would maybe need to disable NAT-T as that uses port 4500 by default when creating the tunnels? But if I disable that so I can create the specific source port, I would need to modify all their other tunnels as well.
Looking for advice on how to best set this up for them. They are using ISR 4K routers.
Thanks
