Problem is when a client connects to guest vlan cannot get ip from dhcp helpers.
hub and spoke network with 12 vlans @spoke location.
all switches point back to single core switch with all vlans and ve interfaces. with 1 default route 0.0.0.0/0 10.48.250.1 to a cisco handoff. I have no control over network after that.
I have been given a firewall address, a vlan name and subnet, 2 helper addresses behind the firewall.
i created new guest vlan on 1 switch in a closet and in my core switch. and created svi in core switch just like all 11 other vlans.
i have wiresharked another port in same vlan and can see discover packets going out but dont see any offers.
i can ping and traceroute the helper addresses from core switch and source ping and traceroute them as well
firewall administrator says he does see pings and traceroute but doesnt see any dhcp traffic.
show ip route shows my default route, and all my ve interfaces as directly connected routes.
1 <1 ms <1 ms <1 ms 10.48.250.1
2 <1 ms <1 ms <1 ms 10.0.0.202
3 <1 ms <1 ms <1 ms 10.0.0.132
4 2 ms 1 ms 2 ms 10.0.0.180
5 1 ms <1 ms <1 ms 10.70.255.254 firewall
6 1 ms 1 ms 1 ms 10.73.0.20 helper address
would adding a static route for guest vlan subnet straight to firewall produce any difference in sending dhcp to firewall?
