Hi all. We have recently upgraded from PIX to ASA5540 and we have seen a rather strange thing going on. In a nutshell we can ping the inside interface of the ASA from any network range on our 6500(which is connected directly behind the ASA on the inside) except one in which our monitoring tools are placed. On the inside interface there is an ACL that permits everything from our core networks but it doesn't help which is really strange.
In the ASDM I can see messages like this:
IDS:2004 ICMP echo request from x.x.x.x to y.y.y.y on interface inside. I don't think that this is the problem but I could be wrong.
Here is also the configuration of the VLAN interface for the VLAN from which we cannot ping the inside interface altough we can ping to and from that VLAN and the machines without problem. The only problem is pinging the inside interface of the ASA.
ip address x.x.x.x 255.255.255.0
ip directed-broadcast 199
ip accounting output-packets
ip pim sparse-dense-mode
ip route-cache flow
Did anyone encounter problem like this before? Thanks in advance for any help.
