Missing something obvious - pppoe with multiple IP address on WAN
-
Hi All,
I'm fairly sure I am missing something obvious here, could someone try and point me in the right direction.
It's a fairly simple setup, router in bridged mode, pfsense WAN connection using pppoe.
Connection comes up and works fine, WAN is assigned an address by ISP traffic flows fine, can reach pfsense box from internet.The ISP provides a /29, in my case x.x.x.24-31, the ppp connection has picked up .30
I have added .25-29 as virtual IP's, ip alias with /29 subnet (I have also tried /32)
I have a 1:1 NAT rule on the wan interface, with .25 external going to 192.168.64.17 internal.
On firewall rules for wan I have an allow any from any to any rule
On firewall rules for lan I have an allow any from any to any rule
(not safe I know but testing...)If I run "tcpdump -i pppoe0 host my.test.ip.address" and ping .30 I see request and reply packets. If I ping .25 I see requests but no replies.
I can ping 192.168.64.17 from it's own subnet.Help...(please)

Honest to god, I hate computers some days.
Virtually the second I hit the submit button on that post (after looking at this for the last 2 hours) it started pinging. No idea what I did but I guess going through and checking the settings to write the post I must have sorted it.
Stand down boys and girls...

I'm back again...
Different WAN interface but got the same problem.IP routes through to the PF Sense WAN but never gets forwarded inbound. I'm missing something here. As far as I can see it's all setup as it should be but I am not getting traffic.

Run a packet capture on the internal interface do you see the ping requests or replies there?
Check the state table for open states using the .25 IP.
Make sure you can ping out from the .25 IP in Diag > Ping.
