NAT mode settings in loadbalancer service annotation

[hanamantagoud]

Hi ,

As per below link , 5 NAT modes are explained in the documentation.
https://github.com/loxilb-io/loxilbdocs/blob/main/docs/nat.md

But at the global level configuration , when we need to set the setLBMode , only 3 are supported.

0 - default (only DNAT, preserves source-IP)
1 - onearm (source IP is changed to load balancer’s interface IP)
2 - fullNAT (sourceIP is changed to virtual IP)

But at individual service level , 5 modes are given.

loxilb.io/lbmode Set LB mode individually for each service. The values ​​that can be specified: "default", "onearm", "fullnat", "hostonearm", "fullproxy" and "dsr". Please refer to this document for more details.

What is hostonearm , fullproxy , dsr mode from 5 NAT modes given in above documentation ?

How to enable L2 DSR mode and L3 DSR mode using annotations ?
