Help!
Now I study about NAT (Network Address Translator), it is a new way about translate IP local to public.
Ok, the point is when I want to install NAT in LINUX, i got error messages like below. I think this is about coding in nat.h. What should I do with the redefinition error?
Thank you for help me.

hi..
First check whether you have declared structs more than 1 time or not.
To check open a terminal and go to the directory containing the source code, using cd command and than execute command
grep -rin "struct ifnet" .
This will list all the lines which contains above structure than u can trace its multiple declaration or definition.
Secondly There can be a change that the header file containing the definition of structures , has been included more than once in a file.

Thanks for the advice. I've tried the solutions but still have errors.
The last time I did that I remark the struct. And I got the error message like this.

eg: Header files are somewhere in path /opt/ipp/include
than u can specify the path at the time of compilation or in makefile using option -I as shown below.
gcc myprog.c -I/opt/ipp/include
where myprog.c is my program to be compiled and the header files required by it are present in apth /opt/ipp/include.
In the Makefile already use the -I option, like this :
nat.o: nat.c $(HEADER_FILES)
$(CC) $(CFLAG) -I$(NETINCLUDE) -DMAX_PACKETS=$(MAX_PACKETS) -c nat.c
any idea?
nat.o: nat.c $(HEADER_FILES)
$(CC) $(CFLAG) -I$(NETINCLUDE) -DMAX_PACKETS=$(MAX_PACKETS) -c nat.c
any idea?

Dear varsha0702,
I've copy file that needed in the appropriate folder. Then, fix another error after copy those files. But, now I got strange error. This error comes from the main program of nat, that is nat.c. If I compile with gcc from Linux, nothing problem with this nat.c. But, now I want to compile the nat.c with gcc from SimpleScalar, and got this error. Here's some errors :
