I have not been able to determine how to configure a firewall for IPv6 with Comcast Ethernet Dedicated Internet. I can't seem to find a useful guide. How does this normally work? I've been told by tech support that I should have a /126 for a point-to-point subnet and a /48 for my own use, which woul

For about a month now, we have been experiencing a steady 4-5% packet loss rate on our connection, which is noticably impacting voice/video calls, streaming, and online connectivity to applications.  On top of that, we have had to reboot our router a few times for our local network routing, and we a

Good Evening, It has come to my attention that our business gateway's admin password is no longer the default one, we have no evidence of the password being changed, cusadmin - highspeed and cusadmin - CantTouchThis do not work, please reset our gateway. Thank you,Omar

I was wondering if there is a functional test for this piece of the puzzle? The reason I ask is because a Comcast contractor is here replacing my outdoor cable line and the cradlepoint never got online sofar its been 25 minutes.

Hello,I was wondering if it's possible to give callers more than one option to press while in a user's voicemail. Such as say a user in a department is on vacation and would like callers to dial a different user in their department to assist the caller, without having the caller needing to hang up a

I need to get a PTR record set up. I tried last week to just send a PM with my info to Comcast_Joseph without posting here, but that doesn't seem to have gone anywhere. So who do I need to PM to get this done?

I need to have a PTR record created for my email server as follows:   * Removed Customer Information *   It would be great if this could be done ASAP, so any help would be appreciated.   Thanks,   DLO for RJ

We are having problems staying connected, constantly getting bumped off our cloud data base, not able to connect to the internet or the connection is very slow. Any thoughts?

Could you please assist us in updating the PTR for our static IP address?

I've had Comcast Business service for just shy of 2 days. About 4 hours ago it stopped working, and I've been trying ever since (using a tethered phone for access) to find someplace on comcast.com that might either give me a status report, document the outage, let me chat with a business chat person

I have the Comcast modem connected to a Meraki router.  Once in a while, I don't have access to the internet.  When there's no Internet, I can ping the internal Meraki network, plus the Meraki's LAN 10.1.10.4, but I can't ping the Comcast's gateway LAN 10.1.10.1.  The light on the modem says online.

I need to update a few records for my RDNS,  but the system won't let me send a private message.   What should I do?   I have multiple records to update so I prefer to send a list someplace rather than call in.

I'm just starting to play with IPv6 for services.  I have static IPv4 and IPv6 from Comcast. For some of those services, I would definitely want rDNS set up.   Can I be delegated the zone for the appropriate ip6.arpa to use for my /56?

Since there doesn't seem to be any way to find a support email address on the website, I'll post here... I need to setup a PTR to support email.

I found this offer https://business.comcast.com/exclusive-online-offer  $49.95 a month for two years business internet .   Scheduled installation and when the day comes I called them to make sure technician will show up. Customer service told me my installation was cancelled. I asked why?

Hello, My company is haivng email sent through our static Comcast IP rejected from several spam blockers for the reason "554-bad dns ptr resource record".  What do I need to do to resolve this issue?  Thanks,Robert HarroldCastle Creations Inc.

Some time ago my readable voicemail just stopped working.  (March 22 was the last time it worked).  When I go into settings, if I try to turn on Readable Voicemail and Voicemail Notifications, as soon as I hit "Save" it turns everything off.  Every single time.  I have tried doing it in all differen

How do we update / change the caller ID display name?  When we call from our Comcast voice lines, those we are calling receive the name of a retired employee on the caller ID.  We would like to update the caller ID display name to just display our company name.

We seem to have continued outages with our services in the Las Cruces, New Mexico area.  We are now on day 2 of very slow upload speeds and therefore are unable to get much business done.  I would like to speak with a representative concerning the recurring outages in the area.
