VLAN interface created on switch but not able use internet access and ping to firewall. Model - Entrasys B5 switch.

[vijayk]

I have separet DHCP server in network. I created separate VLAN xx for accessing and created VLAN interface on switch with specific IP 10.10.20.xx/xx. For this i set ip helper on switch and created different scope on DHCP server.
Now am getting IP to system from DHCP when i connected to switch port, also am able to ping from system to Switch, DHCP server but not able to ping Firewall.


What will be issue, anyone can help me?

So you have?

• IP (DHCP) on Client, connected to B5 Switch
• Client can ping B5 Switch
• Client can ping DHCP Server
• Client can not ping Firewall

My questions:

• Is the client and B5 Switch and DHCP in the same subnet as the client?
• Is the firewall (IP you cannot ping) in the same subnet as the client?
• Can you ping the firewall IP address from another IP in the same IP range as your client?
