| IPMap and Pinhole at the same time? Hi All,
I've been using my Cayman 3546 router for a while now (1+ years)... Works great. I use SBC as my provider with 5 static IPs, utilizing NAT.
For one of the IPs I use an ipmap to a linux box with a registered domain/etc... So all traffic to that domain is routed to a specific system with multiple types of servers, etc... The other IPs are basically not used at the moment. This currently works.
I also want to setup another system for one of the other IPs (or for all of the other IPs, doesn't matter at the moment) for a specific service, that service may or may not be one that also exists static IP used in the IPMap. However, I do NOT want to allow everything through to this system, just what I specify.
For example, I may want to have FTP Servers on both systems. The servers would not be related to each other, would not have anything in common with each other or anything like that.
Could I set this up using an IPMap as already setup to allow everything through and then create a pinhole for the ftp server? Would the pinhole override the IPMap sending all FTP traffic to the second server or would they both work sending the traffic to the correct server? Should I set this up differently? (note: The linux box is not setup as a gateway/firewall or anything like that nor was I planning to do it, I would prefer to use the router for that).
Thanks,

none | won't work. ipmaps map other ips to a device inside your network. pinholes open ports on your WAN ip to a device inside you network. an external ip can be ipmapped to only 1 device inside, and that device CANNOT have a pinhole forwarded to it.
to do what you want, you MUST either ipmap another of statics to the other machine and use a software firewall on it to block all other ports, or create a pinhole to it using your WAN ip as its public ip.
