Q: I hope you take the time to answer this. I have been searching and searching for the right answer to this and nobody can, even Verizon. I want to go with FiOS for our new office. I need multiple IP’s. But what I got was 5 IP’s with a 255.255.255.0 subnet mask. It should have been 255.255.255.248. This concerns me. I need to host email, Citrix, VoIP services, VPN, etc. I want to use my own firewall to NAT those public IP’s to internal resources. IS this indeed possible? I can’t get a straight answer and I want to dump Comcast.
I have a few other questions about this as it relates to my situation.
1. What equipment should I use of theirs?
2. I have my own firewall (Fortinet 80c) and no router since we currently have Comcast at our existing location. How do I configure it so that I can NAT the public IP’s to internal resources?
3. We also want their TV and I read where it doesn’t work (Static IP) if you have their TV service on the same ONT. Thoughts?
Basically I want to know if I can set it up the same way I have it now with Comcast. Their cable modem acts like a router and I think it may be double-NAT’ing (since the actual internal IP is on the 10.x.x.x). Any more you can shed on this would be greatly appreciated. Comcast was set to provide our service at the new site but they lied about the install date and now it won’t be ready until a month after our move date. So, I need another solution fast.
A: Verizon is a bunch of tards.
Yes, they give you a /24 mask for some reason. Don’t use it. Put in your router 255.255.255.248 (/29). Don’t use the .1 gateway either. Use the first IP of the subnet they gave you. in my case:
71.244.45.152/29 is what verizon assigned me.
71.244.45.152 is my network ID
71.244.45.153 is the default gateway.
71.244.45.154-158 are my usable IPs
71.244.45.159 is my broadcast address
Ignore their t
echs. They know nothing. TheGeekPub.com and about 100 other websites run from there along with mail, VoIP and more. Works perfect. No thanks to them.
I’m not familiar with the Fortigate or any ONT settings for IPs. It wasn’t something I encountered.
On the Cisco:
conf t enter conifg mode
int f 0/0 change F0/0 to your WAN interface
mac-address 12345678 change 123456788 to the MAC of your Verizon actiontec.
wr me save the changes
- Verizon business will setup the DNS PTR records for your IPs to anything you want. Just submit a help desk ticket.
- MAC caching is the only problem. They cache MACs for six hours. So changing your router is difficult unless you just spoof the old MAC (which I do).
- You do not need ANY of their equipment. Period. Just plug your Router/Firewall into their ONT.
- For FiOS TV, just plug their DVRs into a MoCa switch and plug that into your router. I do that too.
