Cant access internet after adding 2nd Wan connection

gme

hi there.

I have added another NIC to enable us to use our ADSL line as a fail over in case our main internet connection goes down.

2nd wan interface is allocated IP from ISP DHCP, it gets and address OK. however when I followed the guide to setup fail over it didn't work when I disconnected Wan1. Therefore back to basics… can I route over Wan2 to get the internet...

I tested the above by setting the gateway to the ADSL WAN2 interface in the firewall Lan Rule. However even after resetting states I could not ping 8.8.8.8

I am getting traffic in and out because I also setup some port forwarding to a web server to come in on the ADSL public IP address and tested this OK from an external computer.

Any ideas why I cant get out to the internet on WAN2? once this is resolved I am hoping that fail over will work.

NB running absolute latest snapshot which I updated today

Thanks for any advice

show us your "routing groups" and your firewall rules.
are you using squid on this machine ?

thanks for the reply.

Surely routing groups is irrelevant at this minute because I am just testing to send traffic out via the ADSL line.. When this has been verified working I will then create the Routing group again. There is currently no routing group setup since I reverted back to a Backup config I made after installing the 2nd NIC

Firewall rule for lan is
Proto Dest Port Gateway queue

* * ADLSGW none

we are not using squid.

Oh, I'm sorry. I didn't realize that you just use one WAN.

Did you change your ADSL-WAN as default gateway ?
SYSTEM -> ROUTING

Is the firewall rule you created in top of all other rules so it could be applied and not an other rule?

We have 2 Wans but I am trying to get everything to go out on the "new" adsl backup line which is WAN2.

I havent set the ADSL as the default gateway. I just changed the Lan Firewall rule to push all outbound traffic through the ADSL gateway but I then cant get to internet access.

I can however still get access OK from a remote machine that browses to a web page I have setup for port forwarding on the ADSL public IP.

perhaps the dns servers of your WAN1 ip are set…..

it happens a lot that isp's only allow their customers to use their dns'.

Set dns to 8.8.8.8 (google public dns) and see if that sorts it out

This couldn't be the problem, because he couldn't ping any public IPs.
