Cisco VPN and Virtual Machine over Bridged Ethernet issues in Leopard

Ok, this is starting to seriously get me down. So much so that I'am conidering bailing on Leopard and returning to Tiger.

Since upgrading my system from Tiger to Leopard, I have been experiencing the following issues, which now all seem to be related:

1. Parallels 3.0 networking over bridged ethernet. No access to guest OS from host over IP, at all. Same problem with all builds, including 5584.

2. VMware Fusion 1.1.1 networking over bridged ethernet. No access to guest OS from host over IP. Can access host from guest OS over IP.

3. Cisco VPN Client connects to PIX and authenticates fine but, once connected to VPN, I cannot connect to any service over IP. No ping. No SSH. No nothing!

I'm using the latest version of Leopard. It was a clean install, too. I'm using the latest builds of all the softwate mentioned. As far as Parallels and Cisco VPN Client are concerned, they work perfectly under Tiger.

This is starting to look like a routing issue. It affects me when wireless or wired into a network. In all other regards, my Mac operates as I'd expect and I have no other issues with connectivity.

Very frustrated. Not exactly what I'd expect. All of my Windows colleagues are fine; their systems "just work" as they like to tell me.

Does Apple have any light they can shine on these issues? Do any of the audience have similar problems and solutions they could share?

Thanks.

OK 😉

First, your VPN client is even newer than mine. Forget that ...

Second, you could try to change the default route manually.
I am not at my Mac at all, so I cannot check the exact syntax,
It should be something like:

sudo route delete default
sudo route add -net 0.0.0.0 <gateway>

And replace "gateway" with your VPN gateway.

What looks strange is that you have two vmmnet networks.
Maybe I'm just stupid.

To revert, use the same commnads, replacing gateway with 192.168.0.1.
This is not a solution, I know. But maybe you want to try.

Cheers
