Unable to access internet from remote site
-
to check for a dns problem you could do something like this.
from shell tcpdump -i if2 dst port 21
from a client ftp://204.152.184.73/
By that your can see what happens on IF2 when you logon to a ftpserver
–--------------------------------------
http://your-pfsense-ip/status.php
you might find something under pfctl

Tried some 1:1 NATing.
Worked like a charm for all our subnets except the remote subnet which we have the trouble with.
Starting to think that there must be something fishy with the router thats handling that subnet.More info later.

Hi Perry,
Here's the result after dumping it to a file and then importing it into Etherreal.
-
did you try searching in http://your-pfsense-ip/status.php for 10.58.202.21 or 204.152.184.73 after the test, there must be some info there telling us what happens ::)
your can also use
Diagnostics -> Packet Capture
to trace ip's -
Here is what I see in status.php during a attempt to connect to an external ftp site.

For me it looks like it nat's to the wan instead of going out
tcp In 10.58.202.21:3530 127.0.0.1:8021 external_ftp:21
should be
tcp In 10.58.202.21:3530 127.0.0.1:8021 204.152.184.73:21but since your running nat1:1 i could be completely wrong on how it should look
I'll Better let the dev's step in now ;)

1:1 NAT was only temporarily while testing.
Those rules were removed before getting this status. So it shouldn't do anything.
