Hi All,
I am trying to reduce the number of switches we have on our network. Currently we have 3 switches. One on the public side of the firewall, one behind the firewall, and lastly one after the layer 7 load balancer.
Internet (public IP) - Swich1 - firewall - Switch2 (10.x.x.x) - Load Balancer - Switch3 (10.x.x.x)
I'm trying to reduce the number of switches by using 1 Dell 6248 switch and creating 3 VLANS.
VLAN1 - Firewall - VLAN2 - Load Balancer - VLAN3
I tested to make sure that no traffic is able to traverse into a different VLAN.
Switch 1 and 2 were replaced with VLAN1 and VLAN2. Everything is good up to this point. The moment I connect servers to VLAN3, servers in VLAN are not accessable from VLAN1/2. If I use a separate 6248 in place of VLAN3, everything works.
I'm out of ideas. Can 2 different VLANS be on the same subnet (ie 10.x.x.x)? I need to have all 3 VLANs complete separate from each other as if they are separate swtiches.
Any help is much appreciated.
Regards,
Victor
