This document proposes a solution to PCP Server Discovery problems in Proxy Mobile IPv6 (PMIPv6) networks when both home network traffic and traffic off-loaded to local access network require traversing a gateway implementing NAT and/or Firewall. This draft proposes enhancements to DHCPv4 Relay Agent by introducing a new sub-option under DHCPv4 Relay Option and to PMIPv6 signaling through additional options to Proxy Binding Update/Acknowledgement messages.
