Hello all,
I'm on UTM9 FW 9.105-9 right now.
Short version:
I installes a linux webserver in a DMZ and everything works fine. You can open the http address from the internet.
Now I like to have access to the internet from my webserver for installing system updates and new programs but I don't get it to work.
Long version:
My setup:
physical webserver (NOT the UTM9):
em2: 192.168.100.100/29 - webserver ip for the internet
em1: 192.168.90.100/29 - server ip for client users (intern)
UTM9 Interfaces & Routing:
Interfaces:
eth8: permanent ip [195.171.192.81/29] - this is the ipaddress for internet users to reach the webserver
eth7: DMZ GW [192.168.100.97/29] - the webserver is connected to this port with em2
eth5: intern GW [192.168.90.97/29] - the webserver is connected to this port with em1
eth2: intern [Trusted] [192.168.48.0/24] - the intranet clients (over a switch) are connected this port
UTM9 Network Protection:
Firewall / Rules :
1: intern [Trusted] (Network) >> HTTP / HTTPS / MySQL / SSH >> webserver INTERN [Host: 192.168.90.100/29] - intranet client access to the webserver over http/s, MySQL and SSH (puTTY)
2: Any >> HTTP / HTTPS >> webserver EXTERN [Host: 192.168.100.100/29] - internet user access to the webserver (195.171.192.81) over http/s
3: webserver EXTERN [Host: 192.168.100.100/29] >> HTTP / HTTPS >> Any - update access from the server to the internet over http/s
UTM9 Network Protection:
NAT / Masquerading: intern [Trusted] (Network) >> intern GW [eth5]
NAT / NAT: 1: DNAT | Any >> HTTP >> permanent ip [eth8] (Network) | Action | Destination: webserver EXTERN [Host: 192.168.100.100/29]
NAT / NAT: 2: DNAT | Any >> HTTPS >> permanent ip [eth8] (Network) | Action | Destination: webserver EXTERN [Host: 192.168.100.100/29]
NAT / NAT: 3: *boom* I'm lost...
For NAT/NAT rule #3 I don't know exactly what to define. This one should be for the internet access from the server to the internet; for system updates and new programms.
I tried rule #1 as SNAT in the other way around (e.g. permanent ip [eth8] (Network) >> HTTP >> Any | Action | Destination: webserver EXTERN [Host: 192.168.100.100/29]) but it didn't work out.
I tried also some different versions SNAT/DNAT and addresses, networks, hosts, but I can't get it to run.
So please enlighten me with a hint or the solution. Pleeeease.
Thanks
