[Openswan Users] SSH freezes, openswan to Stonegate

[Vladimir Hernandez]

Hello all,

We have an IPsec tunnel between a Linux box (Ubuntu Hardy) and a Stonegate firewall. We can ssh through the tunnel, but once we have a working shell, it freezes after some 8 commands. It seems to be data-volume-related, since a 'top' command freezes it immediately.

Here's my Openswan config:

conn tresm-knx
    auth=esp
    auto=start
    authby=secret
    type=tunnel
    keyexchange=ike
    pfs=no
    left=ubuntu.public.ip.address
    leftsubnet=192.168.131.0/24
    right=stonegate.public.ip.address
    rightsubnet=10.154.200.0/24
    keyingtries=0

The Linux box has Shorewall 4, but it freezes even if shorewall is stopped

Is there a setting I am missing that allows for a fluid data stream? Or the other way around, something I have is preventing the data from flowing?

I have the Stonegate side set to no compression, however I do not know if Openswan, in absence of a declared setting, takes a default configuration that may be conflicting with the tunnel's operation.

All and any help with this issue is greatly appreciated.
