Email from someone claiming to be a comcast business representative is "sus", as the kids say...

I recently received an email at the address I use exclusively for sending and receiving email from Comcast that claims to be from a "National Sales Director" for "SMB Solutions" and includes a Comcast Business logo and privacy footer, however the From: address is not from a comcast or xfinity domain

@DofTNet_Enterprises Thanks for reaching out and alerting of that phishing email you received! Great job at checking the email domain! The best way to report this is with our security team. I have a link for the direct website at https://internetsecu

@DofTNet_Enterprises This actually worked perfectly for me. Thank you for digging into this! I tried this on OPNSense (22.7.6) and even did a release/reload (Interfaces -> Assignments) & got the same prefix. I left the script fie

Inbound Traffic on Gateway IP

So I just got Comcast Business with 5 Statics. After some (lengthy) experimentation, I finally got my static IPs sorted out by assigning each of the 5 statics as a separate IP on the IPv4 interface of the NIC for my Windows Server box (also ordered a multi-port NIC) and then using True Static IP Po

I had the "5 static addresses" for years and recently upgraded to the "13 static addresses" along with faster service. When you get static addresses, you are essentially assigned a 2, 3, or 4 bit subnet (i.e. a /30, /29, or /28 in CIDR notation)

I run OPNsense which is a fork of pfsense, but I don't know how much it's diverged since the fork. In case it will help, I posted some details on my setup here which covers how I set up my WAN interface and I can add some additional details on how I

Prefix Delegation w/ CGA4131COM working?

My previous gateway was just swapped out due to connectivity issues, and I can't seem to get prefix delegation working quite right on the new box. I'm running pfsense as my router. I seem to be getting correctly delegated prefixes from the gateway via dhcp6. Digging around with tcpdump I see the C
