we have
1-A wireless link (pre-wimax) that provide me with 2 Mb internet connection (tagged Ethernet frames) throught RJ-45
2-have 6 real IP _one of them as Gateway
what i need now is what is the best and cheapest device to do NAT and DHCP to allow users to access the internet , i am trying to do this using Cisco AP 1141 and the link is working fine with static ip configuration on my lap (give my wireless NIC real IP) but now i just need device to do NAT and DHCP
my suggestion is can i use Cisco RV220W Wireless-N Network Security Firewall to do this function
is the WAN port on this router support tagged ethernet frames ??? or even untagged frames
and can i give this router one of those public IPs and give the rest of those IPs statically to other devices on the network
any help will be appreciated

Hi Mahmoud, the RV220W does not support tag ethernet frames on the WAN. The SRP500 series does.

Thanks Tom for your help
and kindly advice on those questions below and the below scenario
1- is the WAN port on this router support untagged ethernet frames ?
2- can i give this router WAN interface one of those public IPs and give the rest of those IPs statically to other devices on the network
WAN Interface to the pre-wimax device-----------2nd 10/100 port----------Router----------1st 10/100 port ------LAN interface users (DHCP )
NAT on router to translate from private IPs on LAN interface to public IPs on WAN interface
thanks in advance

Hi Mahmoud,
1- Yes, untagged ethernet frames are fine
2- Yes, the router supports one to one NAT and DMZ functions which allow this proposed set up

Thanks Toms for your help and support
so the SRP521W can be suitable for this solution as i think
connect the pre-Wimax tagged ethernet cable RJ-45 to the WAN port and make this port tagged in this 802.1Q frames
and then do a DHCP pool for the private IPs on LAN ethernet ports and make a NAT translation from private IPs to Public IPs
is this correct??
Thanks in advance
