Losing internet connection over time
-
There's this new setup of pfSense I have with a /27 range of public IP's, assigned through Virtual IP's with NAT 1:1.
It loses internet connection in about 3-5 hours. I have no idea what's wrong. I checked ARP table and noticed the MAC addresses, guess that's not normal?

That sure is alot of IPs on one MAC…
I'd have thought that a 1:1 relationship between MAC and IP in ARP table would be better...
How many WAN nics do you have?
Your ISP gave you 20 IPs right?
-
Exactly, I don't know why they got the same MAC address. In the DHCP screenshot you can see they are different.
-
How did you assign the IPs? Did you use Virtual IPs for each public IP or what?
I'm Not sure what you have going, but you should not have a DHCP server running on your WAN interface.
-
Private IP's automatically assigned by DHCP in LAN.
Public IP's manually assigned to Virtual IP's.
Virtual IP's linked to private with NAT 1:1.
WAN is the first public static IP, no DHCP.
-
The VIPs inherit the MAC from the host interface. If your upstream ISP has a problem with it (it may) you can try spoofing the MAC on the VIPs.

Yeah - That sucks having the MACs all the same like that.
One would think it would cause issue. I would definitely spoof them all different.I take it that this is 2.1? 2.03 gave me horrid headaches with many WAN IPs.
-
Oh my, didn't know we had 2.1! Also, I can't find where to spoof MAC in VIP's. I think I'm going to download 2.1 and try again.
-
Don't download. Upgrade from the firmware panel. Change your upgrade to the 2.1RC and make sure it is the same architecture as what you are running now (32 or 64 bit). Save you current config first.
Yeah - My limited experience with multi-wan IP is that once you exceed 4 IPs 2.03 starts having issue. At least it did with me.
2.1 has been great.
-
Just upgraded to 2.1.
Nothing is connected to the internet now, not even pfSense, but direct cable from modem to computer does.

You probably need to restore your settings… Worse case, set pfsense to default and reconfigure. If you have done it once successfully, second time should be very fast. Also, make sure you set up DNS. People often think they have no internet but really they do.
If you open the gateway monitor, is it online or offline?
