Have both providers announce using BGP. That way a single IP on the mail server will have path redundancy and switch automatically to the provider that is still up. At least one way redundancy.

We have 2 different sat provider (one way), each gave us a c class. depending on which source ip we use, the return path will be via one provider or the other We have 2 ips assigned to our mail server, one on each network each one with different MX priority. if one sat link is down, the email or the query will arrive on the other link. i am not sure RIP will solve this poblem, but i am sure it will be years before the providers will route their competitors adresses thru their links but again, I am far from being an expert on RIP or BGP, so who knows. :) ----- Original Message ----- From: "Terrence Koeman" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Monday, May 13, 2002 2:27 AM Subject: RE: [Declude.Virus] First post > Afaik it's not possible to set a source IP at all with declude. > > Plus I'd like to note that you really should implement this below the > application layer, ie by using RIP or dynamic routing of some sort. > > -- > Regards, > > Terrence Koeman > > Technical Director/Administrator > MediaMonks B.V.
