Hi,
I am having a very difficult time understanding what is going on with this
FreeBSD machine..
I was having inet trouble so i put in a new router on my network (home
network)..
I have a FreeBSD machine on my network:
FreeBSD yeaguy.com 8.1-RELEASE FreeBSD 8.1-RELEASE #3: Thu Nov 4 20:43:41
PDT 2010 v...@yeaguy.com:/usr/obj/usr/src/sys/HBCA i386
I have windows machines on my network..
One of my windows machines is my laptop and I connect directly to the
router via WIFI without any trouble at all... I can browse any website
without complaint.
My FreeBSD system connects to my WIFI router just fine as well.. I am
seeing troubles browsing the inet with my FreeBSD machine (Xorg and
opera) Pulling up Google.com can take up to 30s..
My Other windows machine is using the FreeBSD as its gateway, I am running
ipnat. This pc suffers from the same issues as the FreeBSD box..
I configured the new router with the same ssid and wepkey.. so minimal
adjustments would have to be made for other WIFI users in the house..
Everyone is fine except me...
My server is fine as far as my Website is concerned.. I changed my DNS
with my host to point to my new WAN IP.. I can pull my page fine.. I can
ssh to my server fine from my phone, phones ip is from my Phones netowrk..
this is not being done via WIFI on my phone..
So my Nat'd WIN PC and my FreeBSD Xorg cannot browse the internet like it
used to.. 30s to 40s to pull up google is just unacceptable, when I have
my laptop sitting here using the same WIFI router pulling it up in about
3ms...
Another odd symptom I am seeing is that when i issue the command 'alpine'
to check my email, it hangs for a good 30s.... So in my mind, Im
thinking, what changed?? My router and my Public IP.. thats it.. its
almost like I have my OLD WAN ip hardcoded somewhere causing a conflict..
I cannot find it hardcoded anywhere..
Heres an example of what im seeing:
[...@yeaguy ~]$ ping google.com

I am unable to browse to nytimes.com via FreeBSD Opera browser or WIN PC
that is using the FreeBSD as the gateway, but I can telnet to it on tcp
port 80 just fine..

I am thinking of doing a fresh install to see if my issue clears.. I am
beyond frustrated.. A WAN IP and router change and now I have some odd
tick/hangup on the system???!!! that makes no sense.. if i put the old
router in place it works fine.. I really dont want to use the old router
either,, it requires a reboot daily.. it flakey...
I checked the router for ACLs and anything that might cause conflict but I
am not seeing anything.. I really cant see how its the new router.. my
WIN LAPTOP when connecting to the router works flawlessly... The only odd
thing I do see in regards to the router and FreeBSD box is the WEP
attributes:
ifconfig shows:
wepkey 1:40-bit // Router shows: WEP Encryption: "64 bits 10 hex digits"..
is that an issue??
Router is a Linksys WRT54G2... My router logs show in and out traffic
from the FreeBSD box.. so this is why Im thinking its the FreeBSD box...
Can i do a system wide grep on all files to see if i find the OLD WAN IP
hardcoded somewhere???
I have completely disable ipfw as well:
yeaguy# ipfw -q flush
yeaguy# ipfw show
65535 4145 3401628 allow ip from any to any
If anyone can assist Id be very greatful..
Thanks
Justin V.
