I'm trying to create a firewall hole for mosh, which requires opening a range of UDP ports.
I can do this if I simply edit the config file, and specify "option src_dport '60000:60020'", but if I try and use Luci, the text entry box turns red as soon as I type a ':' or a '-', and won't let me save the changes.
Clearly this must be possible using luci -- what am I missing?
Oh!! That was my problem. I was so sure that it wasn't accepting the range separator character that I never finished typing the second port number. Probably if I had been configuring 2 digit ports, rather than 5 digit ports, I would have figured it out myself. Oops! Thanks.
