Description (partial)

Symptoms: VPN routing/forwarding (VRF) Network Address Translation (NAT) is not
translating UDP traffic at all. The inside local IP is still used after NAT. If the inside local IPs are not routable on the NAT outside side of the network this breaks all applications relying on UDP. ICMP and TCP traffic are not impacted

Conditions: Occurs when NAT is inside a VRF.
