If I have a connection arriving on Port X from IPaddr A.B.C.D can I forward it
to port 80X?
Or to be a bit less abstract:
If I have a client connecting to port 22 on my server, say from 10.18.18.4
can I use IPtables to sent that connection to Port 8022 on the same box?
At the same time I would want traffic from 10.18.19.4 to arrive on port 22
and be forwarded passed through to port 22.
In a standard firewall situation that's a standard case scenario.
The wrinkle here is the traffic destination is the same box.
How much more complicated does this become if I have 10,000 source addresses
that get the special treatment.
The addresses would be a handful each from thousands of net blocks - think of
traffic from routers and switches getting the special treatment while traffic
from workstations, servers and such are passed through.
