Greetings

I've been running two firewalls for some time now, one Pix serving our web applications and one FWSM serving both users and some web application servers.

After the migration the FWSM is set up like this

Internet

|

|

FWSM----ApplicationNet----PIX(VPN only)

|

|

UserNet

During the migration I pretty much copied all the statics, access-lists and alias entires and adapted them for the FWSM interface names before applying them. No errors there.

Now the old alias commands from the PIX are causing me alot of headache.

The commands I copied lookes something like alias(applicationNetInterface) insideIP OutsideIP. alias(ClientNetInterface) insideIP OutsideIP. Seems ok to me.

But running these on the FWSM causes problems for my incoming internet visitors. I've set up a testing system using 3G and at some point after doing clear xlate I can no longer access my web from my testing system. Nothing in the logs indicating translation errors.

The show connection does however give me strange input.

My static for the web service is like this: static (SERVER,INTERNET) 217.15.245.71 10.91.1.200

But I get connection entries from the outside for both the inside and outside IP

sh conn | include 217.15.245.71

TCP out 218.74.45.91:1916 in 217.15.245.71:80 idle 0:00:12

TCP out 81.234.145.186:1259 in 217.15.245.71:80

sh conn | include 10.91.1.200

TCP out 193.12.113.100:4610 in 10.91.1.200:80 idle 0:00:36

How could this be? On the Pix I used the alias command to allow application servers to resolve the web address to an inside address, something I still need to do, and had no problem with the setup.

FWSM must handle this differently

Any input
