SG3100 WAN IP different to my IP?
-
Hi, I have noticed something I cant figure out.. on setup a dynamic DNS service I noticed that my WAN gateway address is different to the address reported by the DynDNS and also the address reported by say google. Google and DynDNS have the same IP, and the WAN has a slightly different IP - last octet different. All routing works. This is Virgin UK BB. This issue is new as on my Asus router it was fine.

If only the last octet is different are you sure you're not looking at the gateway address rather than the interface address? The dyndns client should report the interface address to the provider.

@stephenw10 Thanks so noob status coming through here. On the dashboard in the gateways panel, WAN DHCP <IP>. I then have in another panel the status for DynDNS and this shows a different IP - Which matches the google search.
Worryingly, the WAN DHCP IP I can ping externally as well :-/ -
The gateways widget shows the gateway IPs. So that's the ISP usually. The interfaces widget shows the WAN IP which is what pfSense is using on it's interface and what the dyndns client should show.
You should not be able to ping the WAN IP from an external host. The default firewall rules block that.

@stephenw10 ah yes just added the interfaces panel, and the IP for WAN is the 'google one', which matches the DynDNS IP shown.
And yes, the IP in the interfaces panel for WAN I cannot ping.
So where can i read more about what this gateway IP is, what can be done with it? And why can this be pinged?

The gateway is what your ISP passes to pfSense to use as the next hop for routing. It's a router at their end of the WAN connection.
