The IP source address is fixed by signaling on the GTP-C control plane and nothing that the kernel can unilaterally decide to change. Such a change of address would have to be decided by and first be signaled on GTP-C to the peer by the userspace daemon, which would then update the PDP context in the kernel. So I guess you're asking us to document that rationale as form of a source code comment ? -- - Harald Welte <lafo...@gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
