Duplicating clients name and IP address of a server
We have two firewalls connected to one L2 switch that is connected to our 2 ISP.
The 2 ISP have a separate VLAN to separate their outbound traffic. ISP 1 VLAN is 1000 and ISP 2 VLAN is 2000. Port 1 of the L2 switch is connected to ISP 1 and port 2 is connected to ISP 2. Port 4 and 6 of the L2 switch are connected to both WAN 1 port of the 2 firewalls, with VLAN number 1000. While ports 3 and 5 are connected to the WAN 2 port of the 2 firewalls with VLAN 2000.
I believe the firewall is configured with VRRP. We are just wondering why port 4 has a 2 IP and duplicates one of the client's names and IP address of our server. Can anybody help us with this?
