This might be the forum section since shrew vpn client isn’t a part of the openSUSE package repository, but I really need help so here goes.
Is anyone familiar with Linux VPN clients and Juniper SSG 5xx firewalls? I did some research about, and most people seemed to recommend the shrew vpn client (Shrew Soft Inc : Home). I followed the specific HowTo regarding Juniper SSG firewalls on their homepage (with some minor adjustment to match our VPN configuration of course), and I was able to get a tunnel up and running.
I also set the rp_filter to 0 in sysctl.conf and made sure the routings were as expected.
However, the virtual interface (tap0) doesn’t get the correct information. Or to be more correct: it gets the correct information but maps it wrong. The broadcast adress is the same as the ip address, and the netmask is the broadcast address.
Example (tap0):
IPv4 address: 192.168.14.137
Broadcast: 192.168.14.137
Netmask: 255.255.255.255
Anyone got any ideas?
