HPE 1920-48G-PoE+ JG924A No Internet In Vlan2 after power cut

[BColston]

Hi and hope everyone is well!
We have a power cut that caused a weird thing that cause my Phones on Vlan2 not having any Internet.

I just cannot work it out why, so need some advice. I have changed the ip ranges.

IP of Computer Network, 192.168.0.0/24
IP of Phone network 192.168.4/23
Firewall 192.168.0.1
HP DHCP Server 192.168.0.2
HP Switch : 192.168.0.20 (VLAN1) , 192.168.4.1 (VLAN2)
HP Switch Port 48 (going to Firewall) Access type.
HP Switch Port 1 (DHCP Server) Hybrid 1 untagged and tagged 8
HP Switch IPv4 Routing 0.0.0.0 0.0.0.0 192.168.0.1
DHCP Server Enabled – Group 1 – 192.168.0.2 Config / Vlan 1 & 8 Enabled on group 1

Firewall has a static route.
Destination IP 192.168.4.0 , Sub 255.255.254.0/23 , Gateway 192.168.0.20 (Switch VLAN1)

VLAN1 Setup on DHCP
Router 192.168.0.1
DNS Server 192.168.0.2
Option 144 VLAN-8;
VLAN1 – DHCP works, Internet work and I can ping to VLAN2

VLAN2 Setup on DHCP
Router 192.168.4.1 (to the ip on the switch - VLAN2)
DNS Server 192.168.0.2
VLAN2 – DHCP works (and phones get all correct informaion), Internet fails, and I can ping the PC’s on the VLAN2 , if I try and ping anything even the gateway, anything on VLAN1 or 8.8.8.8 it times out.

The firewall can ping VLAN2 fine

Not sure what I have done wrong

Hope i made all that clear.

Cheers

Brian

Hi,

Do you have any configuration backup before power cut?

Thanks!

[BColston]

Hi,

No backup that i can find as i have taken them over from another employee, but what i have setup should work and i keep looking at it so need other peoples views to see if they could spot the error.

Cheers

Hi i think so check up your firewall log (or monitor) Vlan 2 follow the firewall while constantly pinging result, or as a different method create a separate untagged interface for vlan 2 from firewall and ip helper address route from firewall

Note: My english is not good i hope understand to me

I  think i understand, so will give it a go and let you know.

Cheers

OK, 

After reviewing the logs I notice the ICMP packets was not gettting through, once allowed on the filtre setup on the firewall all workd fine.

Thanks for you help
