[srslte-users] connect srsUE and srsENB over network

[Alexander Serkin]

Is it possible to set up default route to tun_srsue device and set some
DNS servers?
I see that after attach UE only has a route to the network with
received address and mask configured in [gw] section of ue.conf

#sudo ip netns exec ue1 ip route
10.20.1.0/24 dev tun_srsue proto kernel scope link src 10.20.1.27

nothing else. And no DNS, though i know my PGW assigns DNS address to
subscribers.

I use srsue&srsenb and third party EPC (Cisco Systems).

Thanks for any hint again,
Alex
