Cannot ping WAN Router

[philipp2084]

Hi,

I am new still pretty new to pfsense and am trying to get a dual WAN setup to work. I had pfsense fully working with the following setup using a single WAN connection.

• Netgear DG 834 GT in 'modem' mode connected to WAN interface on pfsense
• WAN interface configured to use DHCP and DNS forwarder enabled.

This was workign perfectly, the WAN interface got assigned a public IP by my ISP and after setting up a few NAT mappings and firewall rules  I even had VoiP working.

I have followed the guide http://doc.pfsense.org/index.php/Multi_WAN_/_Load_Balancing and changed my Netgear DG 834 GT to work in Router mode. When I plug myself in to the netgear box directly I get assigned an IP address (10.100.0.3) and gateway as well as DNS are set to the routers address (10.100.0.254). I can browse the internet and all is good.
When I connect the WAN interface to the netgear router, the WAN interface gets assigned an IP address and the same Gateway and DNS settings, but I cannot gain access if I then plug myself into the LAN interface on pfsense… I checked that block provate networks is unchecked on the WAN interface configuration page, but am stuck now.

One thing I noticed is that I cannot even ping the netgear router (10.100.0.254) from teh WAN interface on pfsense, which has been asigned the IP 10.100.0.5.

Any suggestions of what to try next?

Could you draw a diagramm of which IP-range is where?
