#### Can I disable specific services if 5G functionally is not needed?
From v2.0.x, SGW was divided into SGW-C and SGW-U, and PGW function was seperated into SMF and UPF.
In order to use 4G only, you need to run the process below.
```bash
$ open5gs-mmed
$ open5gs-sgwcd
$ open5gs-smfd
$ open5gs-sgwud
$ open5gs-upfd
$ open5gs-hssd
$ open5gs-pcrfd
```
And the process below is only used in 5G, so there is no need to run it.
```bash
$ open5gs-nrfd
$ open5gs-amfd
$ open5gs-ausfd
$ open5gs-udmd
$ open5gs-udrd
```
However, among these, SMF and UPF are used by both 4G EPC and 5G Core. And SMF has a protocol stack to interact with 5G NRF. Therefore, if you run SMF without running 5G NRF, the following WARNING occurs in SMF.
```
10/08 14:44:03.045: [sbi] WARNING: [7] Failed to connect to ::1 port 7777: Connection refused (../lib/sbi/client.c:450)

10/08 14:44:03.046: [diam] INFO: CONNECTED TO 'pcrf.localdomain' (SCTP,soc#16): (../lib/diameter/common/logger.c:108)
10/08 14:44:06.046: [smf] WARNING: [3c85dd06-0996-41eb-a985-476fa905aefc] Retry to registration with NRF (../src/smf/nf-sm.c:161)
10/08 14:44:06.047: [sbi] WARNING: [7] Failed to connect to ::1 port 7777: Connection refused (../lib/sbi/client.c:450)
```
To prevent SMF from attempting to access the 5G NRF, you need to modify the SMF configuration file as below.
```diff
$ diff -u ./install/etc/open5gs/smf.yaml.old ./install/etc/open5gs/smf.yaml

If you set as above and run SMF, you do not need to run NRF. Seven daemons operate in 4G only state.
#### How to change UE IP Pool
The Open5GS package contains a systemd-networkd configuration file for `ogstun`. Therefore, you must first modify the configuration file as follows.
