PfSense only responds under VIP, not normal IP
-
Hello,
we are running a pfSense 2.0.1 on a cable line.
There is one single IP 213.o.o.9/24 for the router with a subnet 212.o.o.16/28 routed to the single IP used for VirtualIPs.Two months ago the ISP decided to give out the single IP with DHCP for security reasons.
(It's still the same, only with DHCP and not static).Now the pfSense takes one of it's Virtual IPs (from the 212 subnet) as it's WAN IP.
It's not happening at the first boot, only from time to time.I've already tried using the single IP as the "Alias IP address" on the WAN interface settings - didn't help.
It seems like the rc.newwanip works not as expected:Jun 27 03:59:03 apinger: Starting Alarm Pinger, apinger(27639)

This problem is really driving us crazy.
Can anybody help me here? -
help!

Im not understanding fully.
Your primary WAN is now set for DHCP correct?
-
After re-reading Ive noticed some more detail.
on my setup here… one dhcp (primary) and on static (VIP) that my firewall will take its VIP address as its WAN address if I reboot the modem without rebooting the firewall. Since they both run on the same UPS its not generally a problem but just something I keep an eye on.

Yeah, WAN is set to DHCP and gets the same IP everytime (212.o.o.9)
But every now and then (5-15 days) rc.newwanip detects a VIP as its normal IP and doesn't respond with the 212.o.o.9.
Additionally it's blocking access to a random server as it takes one of those IP addresses.
