VIP traffic routing from WAN on PPPoE
I've recently changed to using PPPoE directly on the firewall WAN interface rather than having an upstream router (that was mine) and the FW having a static IP.
This issue "may" have been occurring previously, but if so I never noticed it!
I have a static IP and a routed /29 subnet from my ISP
When I ping a VIP from on the LAN interface (or from the FW Diagnostics), the traffic is passed to the gateway IP assigned by the PPPoE connection and is then reflected back to the WAN interface
where X.Y.1.91 is a VIP on the FW
and X.Y.12.68 is the GW given by PPPoE
and X.Y.28.117 is the IP given by PPPoE
Ping output: PING X.Y.1.91 (X.Y.1.91): 56 data bytes 36 bytes from A.B.C.D.com (X.Y.12.68): Redirect Host(New addr: X.Y.28.117) Vr HL TOS Len ID Flg off TTL Pro cks Src Dst 4 5 00 0054 1b67 0 0000 40 01 995f X.Y.28.117 X.Y.1.91
Do I need to add some form of static route ?
