LxCIPtable VNF Configuration Settings
You can configure the LxCIPtable virtualized network function (VNF) from Configuration > Network Services > Service Name > Overview > Service Configuration.
Your service provider usually configures base settings for the virtual machine (VM) in which the virtualized network function (VNF) resides and you configure settings for the service, such as policies.
Use the information in the following tables to provide values for the available settings:
- Table 1 shows the base settings you can configure for the Linux container.
Note: Your service provider usually configures the base settings and you should not need to change them.
- Table 2 shows the firewall settings you can configure.
- Table 3 shows the Network Address Translation (NAT) settings you can configure.
