Hello guys,
I have a question related, as mentioned in the subject, to NAT-ing ICMP
traffic using ovs and flows.
I managed to create NAT Port Mapping for TCP and UDP traffic, in order
to access the internet from my VM's, unfortunatelly ICMP traffic can't
be port mapped (for example "ping" doesn't have ports).
After a bit of research on ICMP packets I realized that the only way I
could NAT ICMP traffic was if I could map the ICMP Query Identifier. But
I didn't find any reference to it in ovs (the only ICMP related fields
are the type and the code).
I do understand that it would be a bit hard to manage the ICMP ID since
it's offset within the packet differs from type to type, but is there
any way in any version of ovs that has this functionality (I am using
ovs version 2.0.0)? Or is it in one of the future planned patches?
Does anyone have any other solution to NAT-ing ICMP traffic?
Thank you,
--
