Can't ping external networks in the "srsRAN gNB with srsUE" ZMQ scenario.

[Ali78k]

I've followed the instruction in "srsRAN gNB with srsUE" page with ZMQ option and Open5Gs Core. Ping and Iperf tests that mentioned were passed but when I want to ping an external network, I get following error:
Network is unreachable

Also, I've attached the Wireshark captured file.
srsgnb-open5gs-srsue.zip

Thanks for your time.

You need to enable IP forwarding - see section "Adding a route for the UE to have WAN connectivity" here:
https://open5gs.org/open5gs/docs/guide/01-quickstart/

Thank you @pgawlowicz.
I'm sorry I didn't mention this before, but I had enabled IP forwarding according to the link you mentioned.
I also have this problem with Dockerized version in this link.
Isn't it UPF problem? How can I check it?
Thanks a lot.

Did you configure routing correctly? UE needs to have a default route.

Please check the updated tutorial on connecting srsUE with gnb. There is a new part explaining how to configure routes for the PC running the core network and for the UE.
