WNDR3700v3 - Any firmware can disable NAT?

Hi everybody,

 

I just purchased the Netgear WNDR3700v3, which is used to connect to the ISP modem and my firewall x 2 (in HA mode). Actually, this router is originally desired to replace the ISP's router.... because I have to have the network cables connecting the router with my firewalls x2 (in HA mode), but the ISP's router ONLY configured 1 port as the LAN interface (i.e. our external WAN subnet). I have to use my own router to replace the ISP's router with the given config setting, so that I can configure 2 ports as LAN interface to connecting to my firewalls.

OK, back to the question, I found that the WNDR3700v3 seems cannot disable the NAT.... I have to do so because I need to use my own external subnet as outbound IP instead of the outbound IP attached with the ISP's GW.

After checking with the GUI with the 3700v3, and searching thru the forum, I was told Netgear router cannot disable NAT..... does any one know that, any third party firmware or any other way for disabling the NAT? Please help & advise, please!!!!

 

Many thanks!!!
