Hello,

I can access the the web server on the DMZ from the 192 network but not the other way around. It needs to be able to log on to the domain, access shared files etc. What do I need to do? Seems like it would of made life easier to just leave it on the 192 network

Result of firewall command: "show run"

Thanks,

It's only easy when you know how.
 
Not sure why you have a static translations:

static (dmz,inside) 68.217.84.114 172.18.0.10 netmask 255.255.255.255 0 0

Try replacing with

Static (inside,dmz) 192.168.0.0 192.168.0.0 255.255.0.0

I know it looks quirky, but it worked for me.

 
Your going to need an ACL on the DMZ interface allowing this traffic.

pixfirewall(config)# access-list dmz_in permit tcp any host (fileserverip) eq 139
pixfirewall(config)# access-list dmz_in permit udp any host (fileserverip) eq 138
pixfirewall(config)# access-list dmz_in permit udp any host (fileserverip) eq 137
pixfirewall(config)# access-list dmz_in permit tcp any host (fileserverip) eq 139
pixfirewall(config)# access-list dmz_in permit udp any host (fileserverip) eq 138
pixfirewall(config)# access-list dmz_in permit udp any host (fileserverip) eq 137
 
Then apply that to your DMZ interface:

access-group dmz_in in interface dmz
