[webmin-l] Virtualmin - Users on same subnet are unable to connect

[Steve S. <sh...@fu...>]

I have my server setup behind a firewall that is doing 1to1 NAT. (It's a
sonicwall).
 
The external IP address of the server is 206.13.20.5
The internal IP address of the server is 192.168.5.5
 
When a user from another computer on the same external IP network
(206.13.20.x) trys to connect to the server, they timeout.
This appears to be because Virtualmin creates an ETH0:1 adapter with my
external address. I am guessing this is conflicting with the Sonicwalls One
to One NAT feature, as this server is setup as a 1to1NAT.
 
I am not 100% sure why it does this, but when I remove that virtual adapter,
everything still works fine, and users on the 206.13.20.x network can browse
the websites again.
 
note1: Users outside the 206.13.20.x network can always browse the websites,
even with the ETH0:1 adapter there...
note2: It's not just web access, they have no access to the server at all,
everything just times out.
 
Here's the adapter it creates:

eth0:1    Link encap:Ethernet  HWaddr 00:C1:C5:A5:NA:C2
          inet addr:206.13.20.5  Bcast:206.13.20.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          Interrupt:11 Base address:0x1000

Once deleted, all is good.
