+## UE 1 Configurations
+
+**Step 1:** Creating a namespace:
+
+sudo ip netns add oai-2
+
+**Step 2:** Creating a pair of virtual interfaces (veth):
+
+sudo ip link add veth0 type veth peer name veth1
+
+**Step 3:** Moving one interface to the created namespace:
+
+sudo ip link set veth1 netns oai-2
+
+**Step 4:** Configuring an IP address for veth0 interface:
+
+sudo ip addr add 192.168.1.1/24 dev veth0
+
+**Step 5:** Configuring an IP address for veth1 interface within the namespace:
+
+sudo ip netns exec oai-2 ip addr add 192.168.1.2/24 dev veth1
+
+**Step 6:** Bringing up the veth0 interface:
+
+sudo ip link set veth0 up
+
+**Step 7:** Bringing up the veth1 interface within the namespace:
+
+sudo ip netns exec oai-2 ip link set veth1 up
+
+**Step 8:** Adding a route within the namespace:
+
+sudo ip netns exec oai-2 ip route add 192.168.70.128/26 via 192.168.1.1 dev veth1
+
+**Step 9:** Enabling packet forwarding within the namespace:
+
+sudo ip netns exec oai-2 sysctl net.ipv4.conf.all.forwarding=1
+
+**Step 10:** Setting default policy for packet forwarding within the namespace to ACCEPT::
+
+sudo ip netns exec oai-2 iptables -P FORWARD ACCEPT
