Hi all,
I'd appreciate hearing from anyone you could help me diagnose what's
going on here... it doesn't _appear_ to be affecting the rest of Gnatbox
or access to/from it but... I hate things I can't fix!
I am getting some strange filter alarms where it appears that an Aliased
IP address is making a call back onto itself... (at least that's the my
interpretation of it!)
I have included a copy of the filter alarm below:
-----------------------------------------------------------------------------
NOTIFICATION TYPE: GNAT Box FILTER ALARM
NAME: *****
CONFIGURATION: EXT=210.55.93.213 PRO=192.168.4.6 PSN=10.1.1.1
-----------------------------------------------------------------------------
ALARM NO: 43
DATE: Saturday, Feb 5, 2000
TIME: 22:45:05
INTERFACE: lo0
ALARM TYPE: Block
IP PACKET: TCP [210.55.93.211/3884]-->[210.55.93.211/25] l=0 f=0x2
[smtp.logistics.co.nz/3884]-->[smtp.logistics.co.nz/25]
DETAILED DESCRIPTION:
IP packet was rejected.
The IP address 210.55.93.211 is set as an alias on the external NIC and
I have checked my tunnels and filters and they seem OK. Relavant bits
are below...
- Inbound tunnel for TCP 210.55.93.211/port 25 through to 10.1.1.21/port
25 (email server on PSN)
- Allow the Internet access to Asset's Email Servers Accept EXT
TCP
from 0.0.0.0/0.0.0.0 to 210.55.93.208/255.255.255.248 25 110 (I
have a couple of email servers on differnet IP address' - this seemed
the logical way to do this...)
Any help would be greatly appreciated.
TIA
Oh... Gnatbox version 2.2.0
