I have a 4006, with multi vlans...all working.  However when I added a new vlan  the traffic on the new vlan only permits 1 device to get to the outside world and be seen by other devices on the other vlans.  PCs on the new vlan can see each other and ping.  Trace routes from the one working device have 1 hop to the
vlan gateway then distination.  Trace routes from any other device on the new vlan time out, with no 1st hop.
any help GREATLY appreciated, thanks in advance....

Do the non-working PC's have the proper default gateway set if you do an ipconfig?  Their default gateway should be 172.19.30.254.

The non-working PC's are all set to 172.19.30.254.  I set a range from our DHCP server to hand out all the proper info gateway...etc.  Which is surprising being that the DHCP server is on a different subnet other than the 172.19.30.0/24 and pings time out to that address from the PC's....weird?

172.19.30.254 its your default gateway.
You need to setup dhcp relay agent on the vlanxx2
ip helper-address x.x.x.x your dhcp ip address

Very strange, so obviously traffic is flowing if you are getting DHCP from the server on a different subnet.  Is the issue specific to ICMP?  Can you ping the gateway even?  Can you access a web server?  Could the Windows Firewall be blocking ICMP....

Well turns out it was a VPN client issue?!?!  Thanks for the input!  Disabled the VPN client and everything was fine.
