ZyWALL USG100-PLUS - Dual Internet acess

NRdroque

Hi everybody,

i have a ZyWALL USG100-PLUS and have configured with one ISP router, last week due to contract change and increase of users we now have another ISP router that are not in use.

My question is if is possible to configure the 2 routers:

Case 1:

configure the second one as backup in case of failure of the first.

Case 2 :

doble the speed

Hi @NRdroque,

Case 1

For case 1, you can add a new wan trunk to configure the second ISP as backup in case of failure of the first ISP.

Go to CONFIGURATION > Network > Interface > Trunk > User Configuration and click Add.

Suppose wan1 is connected to the new ISP router and wan2 is connected to the old ISP router, set wan1 as Active and wan2 as Passive.

After new trunk is created, select this new created trunk as the default trunk in CONFIGURATION > Network > Interface > Trunk > Default WAN Trunk.

Configure Connectivity Check in CONFIGURATION > Network > Interface > Ethernet > wan1 and wan2.

Select Enable Connectivity Check.

Select Check Default Gateway or Check this address.

If you select Check this address, enter a valid IP address such as Google's public DNS server 8.8.8.8.

Case 2

You can use two ISPs simultaneously and configure a new wan trunk for load balancing but not for doubling the speed.

Select the load balance algorithm.

Specify the weight (1~10) for the interface if weighted round robin is selected.

The higher an interface’s weight is (relative to the weights of the interfaces), the more sessions that interface should handle.

HI @Zyxel_Emily,

Thank you again.

It's working fine.

I configured as backup

Hi @Zyxel_Emily,

i have detected a problem.

i have the url mailserver.mycompany.com redirected to the ip of the old ISP connection, and then a firewall rule route to my mailserver.

when i have both connections enabled i cannot reached the mailserver.

sorry if i cannot express this problem well
