Redundancy in the LAN

[dom.a]

Hi experts,

I am consolidating a LAN architecture as you can see in the topology attached. I have applied all the required functionnalities as HSRP, M-Spanning Tree, L2 Etherchannel, Trunks and so on. My big problem is that traffic from the Firewall cannot reach devices into the LAN (but can reach device gateway). And traffic in the reverse path (from devices into the LAN to Firewall) is OK.

I am afraid that i miss something, and spent days to troubleshoot it...

need help,

regards

Hi,

You need a couple of static routes on your firewall to reach 10.10.100.0/24 and 10.10.200.0/24 subnets

something like these:

ip route 10.10.100.0 255.255.255.0 10.10.150.254

ip route 10.10.200.0 255.255.255.0 10.10.150.254
