#### Additional Troubleshooting
|
||||
|
||||
After successfully attaching the UE (e.g. `45.45.0.2`) to the EPC if the UE device doesn't have access to internet,
|
||||
it is recommended to do the following checks:
|
||||
- Check if the interface connected to the internet is correctly `NAT` with the `ogstun` interface. Follow the documentation [Here](#UEInternet)
|
||||
- Ensure that the packets in the `INPUT` chain to the `ogstun` interface are accepted
|
||||
```
|
||||
$ sudo iptables -I INPUT -i ogstun -j ACCEPT
|
||||
```
|
||||
- Check if the UE's IP can be pinged successfully by performing `ping <IP of UE>` e.g.`ping 45.45.0.2`
|
||||
- Configure the firewall correctly. Some operating systems (Ubuntu) by default enable firewall rules to block traffic
|
||||
- Explicitly disable it to see if it resolves the problem of granting data access to the UE by doing
|
||||
```
|
||||
$ sudo ufw disable
|
||||
```
