Hello

Question,  I have an ASA 5505 with one vlan. I have created a DHCP superscope on our Microsoft server 192.168.1.0 192.168.3.254

Clients get the right IP however Clients can not communicate between subnets they can ping out to 8.8.8.8 but not google.com

192.168,3.5 can not communicate with anything on 192.168.1.x

No router between asa and clients all switches are cisco L2

Anyway to overcome this ?

Create vlan 2 with 192.168.3.0/24 on switches and asa ?

more info is required to have a better understanding about your network topology and requirements.

for one subnet or multiple subnets?

basically it means all subnets can go through their default gateway and reach the Internet at IP layer but DNS resolving got issues.

even for PING only?

as default gateway is accessible for each subnet, it looks like inter-subnet routing is not enabled on the central router (not a Cisco device? an internet-facing firewall?).

switches are cisco L2

it seems to be the reason why subnets can't reach each other as there is no routing between subnets / VLANs. so what's point for you to create VLANs?

BTW, what's the internal IPs for the clients' default gateway?

Did you create separate /24 scopes for each subnet?

What did you configure on the interface on the ASA?
