Problem with remote extension setup localnet setting

[rchalk]

Following the instructions on FreePBX to set up remote extension, it asks for externip, externrefresh, and localnet settings. The first two are OK, but when I put in the localnet=192.168.254.0/255.255.255.0 line, there is a problem. When I look at Asterisk Info, PEERS, all the external ones show UNREACHABLE, and when I look at the op panel, they are all grayed-out. However, all registrations appear to be normal. Is this a reporting problem, or is there something actually wrong with these settings? Thanks
