win98 browsing problem across VPN subnets
I have just setup a VPN connection three sites using IPCOP.
Everything seems to be talking ok, apart from browsing the network neighborhood. There are no NT/Win2K/XP servers running on any of the sites, all sites are just running win98 pc's using tcp/ip. I have tried configuring all PC's to be on the same workgroup and setup sharing, but still each site can only see the pc's

MULTIPLE IPSEC TUNNELS
I am have a shorewall firewall and freeswan ipsec running on a redhat 8.0
Linux gateway machine. I have one working tunnel defined, all works well. I
am not clear how to define mutiple concurrent tunnels. I can not add further
interface entries as all the tunnels come in on ipsec0, do I still have
mutiple zone definitions? some of the tunnels will be dynamic roadwarriors

IPSec tunnel mode, through a IPIP tunnel
Hello Gurus,
I am a small problem with routing and here are the details.
Interfaces on my server:
* ipsec0 - 172.19.58.94
* tunl0 - 172.19.58.94
* eth0 - 172.19.58.94
Now, the problem is that there is another host 172.19.58.200. All
communication to 172.19.58.200 should be through tunl0, and all the data
should be secured using IPSec (tunnel mode - because there are more
machines on my

What exactly are you trying to accomplish that Shorewall isn''t doing for
you now?

Shorewall 1.4.0 Beta 2
The second Beta is now available at:
http://www.shorewall.net/pub/shorewall/Beta
ftp://ftp.shorewall.net/pub/shorewall/Beta
Function from 1.3 that has been omitted from this version includes:
1) The ''check'' command is no longer supported.
2) The MERGE_HOSTS variable in shorewall.conf is no longer
supported. Shorewall 1.4 behavior is the same as 1.3 with
MERGE_HOSTS=Yes.

vpn-zone wide open
Hello!
I am using shorewall shorewall-2.0.11-1 on fedora core2
(iptables-1.2.9-95.7). My box has 2 physical nic“s plus one virt. ipsec
interface for a freeswan-vpn connection.
A few days ago, portsentry spit out a lot of connections from windows
clients (port 135, 445). Ooops.
I review my shorewall settings but could not find a mistake. So I took a

SNAT on IPSEC tunnel with kernel 2.6/KAME tools?
Hi,
Could not conceive an working set-up for an IPSEC VPN made with racoon/setkey

traffic from my network to a network segment on the far side.

Still VPN

Ipsec and Proxy arp
I noticed the long standing Ipsec FSwan problem was fixed.
But do you still have to make sure Ipec is not running when shorewall starts
Reason I ask Is I could not get my Dmz working with Ipsec in the equation.

Correct Shorewall version for RedHat ES3
Hello all --
I am trying to get Shorewall, ipsec and RedHat ES version 3 to cooperate.
Before posting any specific problems, I thought I''d find out if I have the
right stuff to work with. (I''ve gotten ipsec to work flawlessly with
Shorewall using RH 8 and 9 kernels, so I have some experience with it.
Shorewall 2.0.12 works fine on this ES 3 box, except for the ipsec part)

ipsec tunnel to netgear fvs318

I''m trying to set-up an ipsec tunnel between a Redhat9 box and a Netgear

When trying to initialise the connection - ifup ipsec0 - I get the error:

This would lead me to believe shorewall is blocking ipsec.

Forward some traffic to VPN
Hi. I am trying to force some traffic that goes to address 203.7.93.94

the same shorewall and freeswan).

Hi list, I am trying to create a VPN between two different locations. On
the first location we have a cisco pix 525 Natting the internal
