Hi,

Ok, assume you track a dynamic port assignment on
layer "n".

Traditionally I had code like this in all my dissector layers 
from layer "n"  to layer "n+k" where k = 3 in my case.

if (check_col(pinfo->fd, COL_INFO)) {
    if (pi.srcport == TCP_STATIC_PORT_x || pi.destport ==
TCP_STATIC_PORT_x ) {
      col_add_str(pinfo->fd, COL_INFO, "protocol n ..n+k ");
    }
.. etc..
  }

This was ok for static port assignment, now I am adding dynamic.

However with dynamic port assignment, the upper layers cannot
update the COL_INFO fields etc.. with static code like that above.

So how does one go about massaging the upper level code to
update COL_INFO fields when the ports are unknown until runtime.

Or do I rip out the checks on pi.srcport || pi.destport
and just do this in the upper layers (blindly).

eg:
col_add_str(pinfo->fd, COL_INFO, "protocol n+1 ");

Thanks / Frank..
