Hello everyone , my Voip ATA, for some reason tries to connect to this server , and the people at Grandstream gave no good explanation. Anyhow I want to block it , sis I do it correctly?
All but the FORWARD rule apply only relevant to the router itself. IOW, any use of the INPUT and OUTPUT chains of the filter table will only affect the router's ability to communicate w/ that public IP. And since the VOIP adapter is presumably NOT a part of the router, but behind it w/ an internal IP of 192.168.30.145, these rules are ineffective.
