I used free5gc-ulcl deployment

the association setup was successful between the smf and up1,up2,upf-b

also pdu session establishment and modification was successful

but i am unable to ping google or 8.8.8.8 using the ue's ip

Hi @Satyam-git-hub ,

You have to UPFs in chain in this case. Did you figured out which UPF doesn't forward ping packets? Could you share eUPF tracepipe logs?

And as a blind hit. Routing between 2 eUPF may be not possible without manual pinging from I-UPF to UPF in order to update ARP table. See #465 for solution.
