I was wondering what the command-
"ip domain name domainname.com" actually does on the router?
Having to enter this in recently to enable communication with an Alarm system company's equipment (via IP/ GPRS) has spurred me on to find out if this command is more than just a tag.
Without it, the customers Alarm system could not communicate back to the Alarm service providers equipment even though the required ports were opened (41001 and 41002) for 2 way communication through to the internal network's address- 10.100.1.101
Please let me know if there is much more than meets the eye with this command.
