Both LSN and L2-aware NAT for WIFI subscribers over wlan-gw tunnels is supported. NAT on WLAN-GW is only supported for locally terminated subscribers and not for GTP tunneled subscribers. NAT can be performed on the same set of ISAs that are used for WLAN-GW functions, by referring to the WLAN-GW ISA group from NAT configuration. Alternatively, dedicated set of ISAs can be used for NAT function by creating and referencing a separate NAT-group. Configuration related to LSN and L2-aware NAT is provided in the 7450 ESS, 7750 SR, and VSR Multiservice ISA and ESA Guide.
