Hello Hannes.

Well thats what i tried, but:

[root@bigip:Active:Standalone] ~ tmsh create net route default network 0.0.0.0/0 gw 191.255.255.1 01070330:3: Static route gateway 191.255.255.1 is not directly connected via an interface. [root@bigip:Active:Standalone] ~

The F5 virtual has no ip in that network (191.255.255.1). Thats why i have to do a:

ip r add 191.255.255.1 dev eth0 
ip r add default via 191.255.255.1

But thats not reboot safe obviousely. I put those two commands in /config/startup but that only works now and then. Any ideas?

thanks t.

    Perhaps an exit interface method will work? Map the route to an external VLAN which in turn is mapped to your external interface in the network config. Apart from the example below, I dont think there are any good alternative methods. "tmsh create net route default network 0.0.0.0/0 interface VLAN_OUT"
