Having trouble with a couple items. First of all, should I be able to ping the inside interface of the ASA from all internal subnets assuming all of these subnets/vlans are directly connected to the same L3 switch? I can ping the ASA inside interface from our L3 switch, but I cannot ping the inside interface from a host on a different internal subnet. I have setup static routing on the ASA [
and verified that I can ping the host [10.10.96.212] from the ASA inside interface [10.30.1.5]. The inside interface is on the 10.30.1.x/24 subnet. My host is on the 10.10.96.x/21 subnet. From the ASA I can ping 10.10.96.212, but I cannot ping 10.30.1.5 from 10.10.96.212. I can however ping 10.30.1.1 from 10.10.96.212.
This leads to my next issue, which is trying to setup the ASA to work concurrently with our current firewall. I'm doing this in order to transition to the ASA. I'd much prefer to cutover inbound NAT a little at a time vs. doing it all at once. Our current firewall is setup at 10.30.1.2 and this is the default route on our L3 switch (0.0.0.0 0.0.0.0 10.30.1.2). So my question is, if I setup an inbound NAT to one of our web servers on the 10.10.96.x subnet, will I be able to get it to route back to the ASA as opposed to ending up in asymmetric routing hell since the default route points back to our other firewall?
Solved the ping issue. The management interface had an IP address on the same subnet 10.10.96.5, which for some reason was causing pings from 10.10.96.x to the inside interface to fail. When I disabled the management interface, pings started working. Is this normal behavior?
