4500x interVLAN. Clients can't ping clients on some different VLANS

Hello,

I have a strange situation on my 4500X.

Clients from some VLANs cannot access resources on several VLANs.

I have this:

 

10.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C 10.99.99.0/24 is directly connected, Vlan55
L 10.99.99.1/32 is directly connected, Vlan55
172.16.0.0/16 is variably subnetted, 18 subnets, 5 masks
C 172.16.0.0/26 is directly connected, Vlan3
L 172.16.0.1/32 is directly connected, Vlan3
C 172.16.5.0/24 is directly connected, Vlan1
L 172.16.5.1/32 is directly connected, Vlan1
C 172.16.6.0/26 is directly connected, Vlan10
L 172.16.6.1/32 is directly connected, Vlan10
C 172.16.20.0/24 is directly connected, Vlan8
L 172.16.20.1/32 is directly connected, Vlan8
C 172.16.100.0/22 is directly connected, Vlan2
L 172.16.100.1/32 is directly connected, Vlan2
C 172.16.150.0/24 is directly connected, Vlan223
L 172.16.150.1/32 is directly connected, Vlan223
C 172.16.155.0/26 is directly connected, Vlan50
L 172.16.155.1/32 is directly connected, Vlan50
C 172.16.200.0/24 is directly connected, Vlan222
L 172.16.200.1/32 is directly connected, Vlan222
C 172.16.250.0/28 is directly connected, Vlan250
L 172.16.250.1/32 is directly connected, Vlan250
192.168.1.0/24 is variably subnetted, 2 subnets, 2 masks
C 192.168.1.0/24 is directly connected, Vlan9
L 192.168.1.1/32 is directly connected, Vlan9

 

From VLAN 55 I can only access VLAN9, cannot access any VLAN with IP starting with 172.16.

Also, VLAN 55 is not accessible from any source with 172.16 IPs but VLAN 9 is.

 

Should I attach the running config also?

Any ideas?

Thanks a lot!

Adrian

Hi Georg,

 

I need specific external IP / IP pools for each VLAN with specific bandwidth management.

So I have an interface on fortigate for   each VLAN.

Didn't think on other solution.

 

Thank you,

Adrian

Hello
You need to review the access-lists pertaining to your PBR policy’s, Begin with removing all PBR policy’s from the SVIs and then possibly look at pushing everything via the internet path and then PBR on specific source/destination traffic to alternative next hops
