Share internet access over LAN/WAN

[balu123]

Should i share internet access through NAT under transparent proxy using pfsense or  is there  any other better method to share internet  over my organisation's WAN which has multiple LAN each having around 100 hosts .
Please mention how to setup the preferred method ,

Thanks

Using your firewall as gateway and using transparent proxy are easiest ways but all depends on what exactly you are trying to achieve. If you can provide some more details, you may get more comprehensive replies.
