port it in osmo-ggsn to have the tests working. As I never used
sgsnemu before, I only patched it to account for the changes in libgtp
but without adding the support for the new feature there.

I think you forgot to attach the "make install" log, which is the

P1 daddr=IPs to the server, the NAT changes
saddr=IP1->IPg. It does the same for saddr=IP2, but the NAT keeps track
of the binding. When the response is received from the server, the NAT
converts back IPg->IP1 and GGSN can again track the pdp ctx as described
in the previous case.
but from my
current knowledge I'd say that this is not a correct setup.
If you plan to have several computers under a given pdp ctx, then use a
NAT before sending them to the SGSN, this way the NAT will take care of
maintaining correct fields for each ICMP packet coming from different hosts.
Hi,
I did a quick look a few days ago but I couldn't find a direct answer to
your provided change.
Can you please send a patch to gerrit so it doesn't get lost? You can
add me as a reviewer, I'll have a deeper look when I have some time.

k you need a capable
kernel and libgtpnl to be able to use it.
Also, it would be nice if you could provide a linux "perf" output on
osmo-ggsn while running your test setup so we can spot possible
optimizations to improve osmo-ggsn performance.

Hi,
to me it looks like you are using a version of TITAN too old. Support
for CSN L/H bits was addded recently, and that's why we switched also
recently to TITAN version 6.6.1 to be able to use it.

Hi,
I guess you mean OsmoSGSN?
What are you connecting OsmoSGSN again? OsmoGGSN? which versions?
Unless you provide a pcap file it's difficult to get a picture on what's
going wrong.

ress from the 12.0.42.0-255 range, which is iirC of local host scope.
Try changing the address pool in the APN config in osmo-ggsn.cfg to
provide a local area network range, such as 192.168.40.100-200. Also
update accordingly the IP address set on the related tun device.

implement, and leave a FIXME/TODO commit instead, like the patch which
