implementing DHCP and NAT on a 2514

rstringer

Level 1

Hello,

I have a Cisco 2514 with IOS 12.x. I also have SBC DSL. SBC provides IP config to all clients on my home LAN via the modem/router. I would like to place the 2514 behind the DSL modem/router. If I do this, can I use NAT and DHCP from the 2514? If so, can someone help guide me in implementing this?

Thanks in advance,

Rich
