Hi guys,

I have 4-5 NAT rules (IIS services), I can't reach our internal IIS from the LAN with NAT address (external address). 
What SNAT/DNAT rule I need if I want to use external address to our internal iis server. Strange thing is I use MASQ LAN > LAN (strange) it works not athervise.
Please help.

    Well, if it works, then go with it.

    I think this probably makes sense.

    We've had some recent discussions on these forums about this... we were guessing it has to do with the spoof protection or something like that.

    I suggest the following rules that work for me:

    DNAT: Any->External(Address)/HTTP Internal(Address) Web Server/HTTP
    DNAT: Any->External(Address)/HTTPS Internal(Address) Web Server/HTTPS
    ....
    ....
    Filters:
    Any HTTP -> WebServer Allow 
    Any HTTPS -> WebServer Allow 

    Also change MASQ That is basically used to Masquarade the internal network (LAN) with a single IP of External network (WAN):
    MASQ LAN > WAN
