Hi list
I wrote two function
i run them on one computer to see if they are reverse
the functions are for tunnel
i insert the addresses to optional ip section with option no. 111 like this:

type 111 , len 12 , src, dst

when i decode them and call the reverse func. it makes all of 12 bytes to 1 
NOOPT option .
but when i traceroute through it by one client
some routers at the end of the path drop my packet
it goes truely to 13th or 15th node ( router and path through ) but
after some routers doesn't accept my packet
i don't know why
the ip checksum is true'
i use  ip_insertoption() function  to do so
when i use the ip_strip option for reverse it  doesn't work at all
thanx
