I am testing the implementation of two ASAs. 5510 has the IPS module the 5520 has the AntiX module. I currently have the 5510 sitting in front of the 5520. The 5510 is running in transparent mode. In my lab I can't ping, http, or ftp to one of my test servers sitting behind the 5520 with the 5510 in place. If I take the 5510 out of the equation all services work. Has anybody used two ASAs in this manner? If so how did you get it working?
