Looking for feedback around MTU sizing over SD-WAN.
We have deployed firewalls with SD-WAN and are recieving feedback pxe boot for imaging pcs over the network is no longer working. It appears the MTU is larger than 1500 and is being dropped.
The images are stored on an SCCM server.
Any experience/suggestions how to handle this?

Hello,
I would adjust the size to one that will allow the traffic.
Network tab -> Interfaces -> Ethernet -> Layer 3 interface you want the adjustment on -> Advanced
Hope this helps.

Does the global MTU of the firewall need to change too?

Hello,
It should not have to be changed. Just the interface if I recall.
Regards,
