Sure, I have more than 18 tunnels to manage here, and the only blocking
effects are thuse that I have volontary encoded .
;-)
I believe that Peter has missed something in the VPN parmeters themselves or
not correctly understood how are his IPtables onto this two IPSec secure
gateway...
Peter, could you post us the content of your "/etc/ipsec.conf" file ?
We can take a look here and verify what is not good.

Hi,
We use firewall and VPN togather to connect around 5 remote sites, and
never encounter these problems. Make sure that port 10,000 and above
mentioned in ur rtp conf files are opened in ur vpn and firewall. also
when u connect from remote site don't use public ip use privte behind
firewall. If still have problem send me more detail and i will be more
then happy to sort this out .

Hi men,
You have some IP ports blocked !
I use SuperFreeSwan and I encounter no problem with this kind of
configuration.
Do you have open all ports on your IPsec gateways ?
Think to have a look to your IPchains or any kind of firewall you are
running in your IPSec gateway.
I use shorewall and it is possible to miss some rules or to let pass few
ports only for protections between sites.
You must describe more your configurations to see what...
Good luck !
