RE: [WhatsUp Forum] DHCP & Monitoring...

Title: Message

The VPN's SHOULD be connect all the time. A good reason for the WUG monitoring. The hardware firewall is supposed to be up and running unless the DEU has powered it off (another reason for monitoring). 95% of the users have trouble plugging in a patch cord. I'm not concerned with the DSL connections but I already have a few Cable modem connections that change every 14 days or so. Dynamic DNS would work only if they kept their PC on 7x24 but they don't. My firewalls don't disclose their DNS names.   Digi International sells a single port device that will do reverse telnet, but I'm hoping to find something similar to the slave "cable testing device".   -----Original Message----- From: Tim Evans [mailto:[EMAIL PROTECTED]] Sent: Friday, March 15, 2002 2:01 PM To: '[EMAIL PROTECTED]' Subject: RE: [WhatsUp Forum] DHCP & Monitoring... Will they be connected all the time? If not, then how will you tell whether the line is down or they have just disconnected? If they are connected all the time (cable modem or ???), my experience is that the IP address rarely changes, if at all.   One option you might consider is dynamic DNS. Essentially, something is loaded on the remote systems that reports the IP address to a central location, which then makes it available via normal DNS resolution. You could then use WUG with DNS names instead of IP addresses. There are many people that offer dynamic DNS service, from free on up. Google for dynamic DNS and you'll find a bunch.   just an idea...   Tim Evans, Sparling 206-667-0509, fax 206-667-0554 -----Original Message----- From: Brian Kelly [mailto:[EMAIL PROTECTED]] Sent: Friday, March 15, 2002 10:29 AM To: '[EMAIL PROTECTED]' Subject: [WhatsUp Forum] DHCP & Monitoring... I hope someone can help me find an affordable device...   In a years time I will have 70+ users at remote sites, all connected to the Home Office via VPN's. All users are behind a hardware firewall. Many users have an internet connection that is DHCP based and the address provided by the ISP will change (static's aren't available) I can't ping the inside address of their firewall (like knocking on the inside of the door when your outside) I need to monitor the availability each remote connection and issue trouble tickets/service notices when the line goes down.     Any ideas? ********************************************************************** Confidentiality Notice: The information contained in this e-mail and any attachments may be legally privileged and confidential.
