Upgrading from PIX to ASA 5512X

Question

Hi everyone,
We are in the middle of upgrading from two PIX's to some new ASA5512X's. To give you some background on the situation we are upgrading these since the PIXs are fairly old. We had one extra that we had to use since one PIX has failed already. The guy that implemented the PIXs orginally was learning how to do so as he went so there is alot of needless config in the PIX, atleast from what I can tell. Another guy that works with me has done some configuration on the new ASAs and has done the majority of it so far. Today we went to install the new ASAs and switch everything over hoping it would work, but that didn't happen. It seems that there is something wrong with our NAT and ACLs somewhere along the lines. The way our network is laid out is that we have two school campus with a site-to-site VPN one is 172.17.0.0/16 and the other is 172.18.0.0/16. We also have a remote-access VPN on both ASA's. When we connected the new ASAs up and brought up the interfaces, nothing on the inside could ping the internet nor the other side. The VPN showed active on the ASA's and each ASA could ping the others outside interface, but that was it. I have posted the configs below. If anyone could help out I would GREATLY appreciate it! Thank you in advance!

Hi Derrick,
I just did the same for a customer; replaced 2 PIX515s failover cluster with 5512X. The NAT change is major with ASAs version 8.3 and later...
here's what you need: a manual NAT rule called twice NAT (policy NAT or NONAT is the old terminology) for the VPNs to work. also add the no-proxy-arp keyword:
nat (inside,outside) source static INSIDE_NETWORKS INSIDE_NETWORKS VPN_NETWORKS VPN_NETWORKS no-proxy-arp
nat (inside,outside) source static INSIDE_NETWORKS INSIDE_NETWORKS RA_VPN_NETWORKS RA_VPN_NETWORKS no-proxy-arp
then the dynamic PAT for internet access (after the twice NATs for VPN); could be a manual NAT like you did, or preferred an object NAT.
you did:
nat (inside,outside) source dynamic any interface
would also work with object nat:
object network INSIDE_NETWORKS
subnet ...
nat (inside,outside) dynamic interface
Same on the other side (except the networks are reversed since the inside network is now what the other side refers to as vpn network and vice versa)
If you don't put the no-proxy-arp, your NAT configuration will cause network issues.
also to be able to pass pings through ASA, add the following:
policy-map global_policy
class inspection_default
  inspect icmp
The asa will do some basic inspection of the ICMP protocol with that config ex. it will make sure there is 1 echo-reply for each echo-request...
hope that helps,
Patrick
