I have problem in the configuration of Cisco ASA 5520, IOS version 8.4. The connection is as follows: LAN network--> Firewall --> Routers with GLBP with virtual ip address. the clients can not ping the virtual interface of the GLBP group, but I can ping it from the firewall, and I can ping the clients from the firewall, I checked the packet tracer it gives :
nat (inside10,outside) source dynamic LAN interface
Forward Flow based lookup yields rule:
in id=0x74331ed8, priority=6, domain=nat, deny=false
The GLBP Routers are configured with natting also as follows:
interface GigabitEthernet0/0 description $ETH-LAN$$ETH-SW-LAUNCH$$INTF-INFO-GE 0/0$ ip address ISP_CLIENT_SIDE 255.255.255.252 ip nat outside ip virtual-reassembly in duplex auto speed auto ! interface GigabitEthernet0/1 ip address XX.XX.0.XX 255.255.255.240 ip nat inside ip virtual-reassembly in glbp 1 ip GLBP_VIRTUAL_IP duplex auto speed auto !
ip nat inside source list 1 interface GigabitEthernet0/0 overload ip route 0.0.0.0 0.0.0.0 ISP_GW
