Your opinion about using rdomain or mpath

[C.L. Martinez]

Hi all,

 I am using an OpenBSD vm to act as a firewall for my laptop and as 
openVPN client to connect to several openvpn/ipsec servers.

 Sometimes I need to stay connected to two or more openvpn/ipsec 
gateways. And at the same time, I need to stay connected to other 
networks in my company (which are reached via default gateway).

 As you can imagine, this scenario present some problems about how to 
setup pf rules and manage different default gateways.

 I see two possible solutions: rdomains or mpath. On the other side, I 
can't make changes on openvpn/ipsec servers due to they are out of my 
control.

 In your opinion, what is the best option: rdomains or mpath? In both 
cases I see one problem: I have only one external interface. How to deal 
with this?

Thanks.
