Oh. :( I thought it negotiated the encryption ok because I see this: [ciscovpn] CCP: LayerUp Compress using: MPPE, 128 bit, stateless Decompress using: MPPE, 128 bit, stateless And capturing on the interface, I see echo req's coming in from the concentrator, but I encounter a routing loop when I try to send across the tunnel. Disabling encryption isn't an option, even for testing, I'm afraid. Original message from Joe Marcus Clarke: > On Thu, 2004-01-08 at 02:49, Chris Jones wrote: > > Hi.
