sorry! the first set of numbers is supposed to be 192.168.222.4, more to add would be that 192.168.222.2 is the gateway and dns of 192.168.222.4

and yes there is a port range. i think thats only the case if it cant connect the the server on 10.10.10.250. but the program i need to use eats all traffic that isnt needed.

so in turn its 10.10.10.250 being the reporting box, 10.10.10.125 being the connection live to the web to hit said reporting box, and 192.168.222.2 being the gateway/dns server of 192.168.222.4.

192.168.222.4 > 192.168.222.2 > 10.10.10.125 > 10.10.10.250

i say this because the last time i had it working it showed 10.10.10.125 as the address for 192.168.222.4(i assume thats masquerading) on the reporting box, and in the inetsim config file it says what ip should be used if inetsim will act as a router for certain traffic

This is a malware traffic analysis box. so it needs to only have this one ip address allowed on this one port so that it can report findings of files run to said box.

the inetsim program also makes its own rules that are pretty annoying. at one point i had it telling me that it was established but wasnt showing activity on the destination server. and now its back to square one. let me know if you need more details. sorry for the typo!

and i have traffic from 10.10.10.250 already accepted, its from 192.168.222.2 that i cant get routed.

oidentd_masq.conf(5)						File Formats Manual					      oidentd_masq.conf(5)

NAME

       oidentd_masq.conf - oidentd IP masquerading/NAT configuration file.

DESCRIPTION

       If you are using IP masquerading or NAT, oidentd can optionally return a username for connections from other machines.  Support for this is
       specified by calling oidentd with the -m (or --masq) flag and by creating an /etc/oidentd_masq.conf file.

       oidentd can also forward requests for an IP masqueraded connection to the machine from which connection originates by way of the -f option.
       This  will  only  work if the host to which the connection is forwarded is running oidentd with the -P (proxy) flag, or if the host's ident
       daemon will return a valid reply regardless of the input supplied by and the address of the host requesting the info  (some  ident  daemons
       for windows do this, maybe others).

FORMAT

       <IP Address|Hostname>[/<Mask>] <Ident Response> <System Type>

       The  first  field  contains the IP address or the hostname of a machine that IP masquerades through the machine on which oidentd runs.  The
       mask parameter can be either a network mask or a mask in CIDR notation.	A mask of 24 is equivalent to  255.255.255.0,  a  mask	of  16	is
       equivalent to 255.255.0.0, etc.

       The second field specifies the reply that oidentd will return for lookups to the host matching the IP address specified in the first param-
       eter.

       The third field specifies the operating system the machine matching the first parameter is running.

EXAMPLES

       <Host>[/<Mask>]		<Ident Response>    <System Type>
       192.168.1.1		     someone		 UNIX
       192.168.1.2		     noone		 WINDOWS
       192.168.1.1/32		     user1		 UNIX
       192.168.1.0/24		     user3		 UNIX
       192.168.0.0/16		     user4		 UNIX
       somehost 		     user5		 UNIX
       192.168.1.0/255.255.255.0     user6		 UNIX
