Similar issue here, would be good to know what resolved this? Thx,.
PMG is behind NAT -> public proxmox host IP vmbr0 with MTU 1500, and private PMG IP vmbr1 with MTU 1450.

Seems to be expected: https://pve.proxmox.com/pve-docs/chapter-pvesdn.html#pvesdn_setup_example_vxlan
VXLAN zone configuration options:
Peers Address List
A list of IP addresses of each node in the VXLAN zone. This can be external nodes reachable at this IP address. All nodes in the cluster need to be mentioned here.

MTU
Because VXLAN encapsulation uses 50 bytes, the MTU needs to be 50 bytes lower than the outgoing physical interface.
