1.doing the impossible: connecting 2 PCs over protected LANs

there are 2 LANs: LAN1 and LAN2 .

Both LANs are connected to internet by ADSL.

Connection is protected by severe firewalls.

I want to connect PC1 in LAN1 to PC2 in LAN2 using HTTP and an external
dedicated server (with static IP) mounting Linux.

The external dedicated server should store packets sent by PC1 to PC2
locally and send them to PC2 on request by PC2, and viceversa.

Slow connection speed is not a problem.

I'd like to know:

1. if this can be done (I am pretty confident about this point)

2. if it has already been done, using which software

Thank you

2.PPP internet connect problems

I am unable to connect to any server via a PPP connection under
VectorLinux 4.0. The same machine/modem/line/ISP works fine under a dual
boot Win98SE setup. I get a successful PPP connection as shown in
"ifconfig" and "/var/log/messages". I have the correct DNS server names in
/etc/resolv.conf. But I continually get "hostname lookup failures" with
ftp, browser, email. I cannot even ping my ISP's website. When I attempt
to ping the remote server IP address listed in the ifconfig ppp0 section,
ping seems to hang, when I stop it it tells me "20 packets transmitted, 0
packets received".

The above problems occur logged in as either a user or root so there are
no permission problems. I also disabled "PortSentry" to no avail. There
are no other firewalls that I can see.

I don't quite know where to go or what to check next. Any assistance
greatfully appreciated.

3.PPP modem problem - can't connect to ISP

I downloaded the 5.1 iso and re-installed from scratch over a fully working
5.0 install.  I did this because I was having problems with CVSup upgrading.

Under 5.0 I had set up my modem connection to work with user ppp to my ISP.
It also worked using the KDE ppp utility.  No problems whatsoever.

Now I have upgraded, I cannot access my ISP.  Please help me diagnose the
problem.

I have a Swann SpeedDemon external modem on COM1.  This configuration has
not changed since my 5.0 install and works fine in WindowsXP and BeOS.

I have followed the install instructions in both the Handbook, and the
O'Reilly Onlamp FreeBSD basics ppp instruction page.  To the best of my
knowledge, the current setup (ppp.conf, resolv.conf etc) is identical to my
setup under 5.0.

My symptoms are:

If I try manually dialling my ISP through a "ppp ; term /dev/cuaa0 ;
atdt[number]" I get a dialtone, ringing out, the normal modem noises etc.
Sometimes it says 'CONNECT 56600', but invariably it drops out immediately
thereafter.

If I try an auto dial using the ppp.conf setup, I get no dialtone, no
connection noises and after 20 seconds or so I get an error saying that
there is something wrong with the Chat script.  I don't really understand
the chat script issue, but I guess it has something to do with the modem
settings in ppp.conf.

Is there a known error/change in user ppp in 5.1 which will cause this
problem.  I have tried a re-install to no avail, so it is not a simple
error.  Have I forgotten to install a critical component.

I am concerned that if I go back to 5.0 and (successfully CVSup) I will get
this problem back.  I would rather not go back to 5.0 because Xfree86 4.2
does not have drivers for my video card.

All suggestions gratefully accepted.
thanks

4.Connection between a lan-connected pc and a wireless connected

5.problems connecting to a lan from another subnet

Hi,
Ive set up two server's using RHEL4:
Linux [pcNAME] 2.6.9-5.EL #1 Wed Jan 5 19:22:18 EST 2005 i686 i686 i386
GNU/Linux

1) one is acting as a Router
2) the other is acting as a development server

Router: two interfaces:
eth0: running on dhcp, ip is 192.168.10.235, also connected to my
office lan
eth1: statically assigned ip: 172.22.1.1

Development server, statically assigned ip: 172.22.1.2

Im able to ping
172.22.1.2   <-------------> 172.22.1.1
172.22.1.2   <------------->  192.168.10.235

I cannot access any service on the office lan or the router from the
development server, but I can access the normal service of ssh and http
on 172.22.1.2. Nor am I able to ping the office lan from 172.22.1.2.

I have shut down the firewall from the both the machines...

Thanks
Danish
