SYMPTOMS
An exception in Ipnat occurs if an ICMP packet is received over a PPP connection. This occurs only on devices with RICS processors that include the Ipnat component.



CAUSE
The problem occurs because IPNAT dereferences a USHORT pointer directly from the ICMP header. For PPP connections, IP headers are not aligned (because of PPP framing), so this occurs only on PPP links.
