We have installed Cisco ISR(ISR_1 and ISR_2) and Cisco FW(FW_1 & FW_2) as per photo below.
I already perform PERMITALL to each FW. So no blocking issue in FW.
We perform test FW_1 to FW_2 (using cross cable)without ISR, all the VLAN able to ping each other.
My question why we not able to reach at VLAN 514,515 and 516 to VLAN 114, 115, 116 after implementing ISR devices.
VLAN 514: 10.5.14.0/24 10.5.14.254 VLAN 114: 10.51.14.0/24 10.51.14.254
VLAN 515: 10.5.15.0/24 10.5.15.254 VLAN 115: 10.51.15.0/24 10.51.15.254
VLAN 516: 10.5.16.0/24 10.5.16.254 VLAN 116: 10.51.16.0/24 10.51.16.254
Is it that issue on FW config or ISR config? Really need help on solving this issue.
