#### 1.2.2 eNB and EPC+HSS on Same Host (**NOT RECOMMENDED SETUP**)
|
|
|
```Please **DO NOT** install EPC/eNB natively on the same machine due to conflicting packages/kernel and so on. IF you have at least 8 cores, 16 GB RAM, then you can try to EPC in VMWARE, while eNB is running natively on same machine. We have not tried this so this might have negative real-time performance, especially if you use USB based SDR like USRP B210```

Next, we explain the setup for running eNB and EPC+HSS on same hosts. Assume the IP addresses of eNB/EPC are 192.168.12.82 respectively. We also assume that the interface with which they are connected together is ethernet (eth0).

- See last section of EPC USER Guide [1] on how to connect eNB and EPC machine without using switch in between and changing interface MTU. You can also try to build a VPN between EPC and eNB machine and set the MTU of VPN interface to say 1600. We have not tried but here is example tutorial, http://blog.boyeau.com/cheat-sheet-establishing-a-vpn-tunnel-between-2-linux-servers/. Please let us know if this works for you on the mailing list with detailed instructions on how you did it. It will help the community

- You can simply change the MTU of both EPC and eNB machines to 1600 and connect them directly. If they are connected together via switch/router, then you need to inspect switch configuration that it does not assemble/dis-assemble packets. We simply recommend to connect them directly to avoid issues with switch configuration which is not easy to document and can result in unpredicable behavior in the network if done incorrectly.
|
|
|
- **TESTED**: Root the phone and manually change the MTU on the phone to 1400 using ifconfig or any other utility once the phone is connected. This will work on Android phones.

- ```NOT TESTED```: Install EPC in a KVM or VMWARE on the same machine running eNB (natively). So, this machine has to be at least 8 cores w/ 16 GB RAM. Then change the MTU of bridge and all its associated interfaces to 1600 and use this interface for S1 link between eNB/EPC. There is VMWARE image you can readily use for this. Checkout the VMWARE image from here, https://gitlab.eurecom.fr/oai/openairinterface5g/wikis/HowToConnectCOTSUEwithOAIeNBNew#example-vmware-image-with-working-core-network-installation-for-47x-linux-kernel. This might create real-time issues esp. with USB based SDRs like, USRP B210, so we have to see how well this works. Community testing will help out with this as every configuration is slightly different. Please **DO NOT** install EPC/eNB natively on the same machine due to conflicting packages/kernel and so on. **If you make this work, please create a tutorial with detailed instructions to help the community to help our open source project**
