OVS doesn't handle this case well. I don't think it will do what you
want.

yes, we are already using that one to send packet across 2 OVS connected
via GRE tunnels and when switched out, will remove GRE header.
Imagine situation where SPAN traffic from some other switch is being sent
as replica traffic to OVS inport (one can be configured as GRE port for
that matter).
GRE and tunnels are implemented in terms of ports, so if you send a
packet received on a GRE port to a non-tunnel port, it strips the
header.

I will check on about GTP ongoing activities (I saw some actitvities on
providing capabilities to match on GTP-C/GTP-U packets).
maybe dumb question, but any pointer on how to remove GRE header (or VXLAN
for that matter) when switching packet from IN port to OUT port and switch
out only internal
OVS doesn't support GTP yet, but I know that there's some ongoing work
on it.
GRE and VXLAN should be fine.
If you need GTP support, maybe the best thing to do would be to help out
the folks who are working on it.

Hello,
thanks for feedback.
I know OVS can truncate payload and that in can modify mac/IPs in header
(i.e. like doing NAT).
I also know OVS can deencapsulate GRE (of VXLAN) when packet is arriving on
tunnel OVS interface (done automatically).
But I was not aware that OVS can remove tunnel headers

Hello,
we would need some functionality on manipulating packets when packet is
exiting outgoing OVS port.
I.e. some actions could be: change/anonymize mac/IPs for src/dst, or remove
some tunnel header (vxlan, gtp, gre), truncate the payload etc.
So, one option can be to write some code than can be
