Hello folks

I would like trying to display all ports from 1 to 40 (and filter out all others).
ip.addr == x.x.x.x && ( ( megaco.termid == "port_1" ) || ( megaco.termid == "port_2" ) || ( megaco.termid == "port_3" ) || ... )

gets too big for 40 ports I tried

ip.addr == x.x.x.x && ( ( megaco.termid >= "port_1" ) && ( megaco.termid <= "port_40" ) )

but it displays all 760 ports that I have

any ideas?

Surely you instead need:

ip.addr == x.x.x.x && ( ( megaco.termid >= "port_1" ) || ( megaco.termid <= "port_40" ) )

?
 

Ignore this, what was I thinking...

You probably need to experiment with what the various comparison (>=, <=, etc)  operators do on strings.
At best it'll be alphabetical, i.e. I seriously doubt "port_11" will be >= "port_4".
