I am in the process of implementing some ip phones in my environment.
I got my new Avaya 5610sw phone last week and set up the VPN in my existing Astaro Gateway. The problem is that the phone has an SA lifetime of 5 days and the firewall will only except 24 hours. I have spoken to support on both sides and neither can be changed. So I am now getting ready to purchase a Netgear FVS338 to sit behind the Astaro firewall. Avaya has tested this VPN firewall and it works with the phones. I got some new ips and I would like to forward all the ipsec traffic coming from the new ip through the Astaro firewall to the Netgear box. I have a T1 connection with a Cisco 1841. I know nothing, absolutely nothing about Cisco routers. Will I have to configure something on the Cisco box also as far as the new ip is concerned? Also does this solution seem viable? The idea sounds good but I'm not sure where to start as far as getting the traffic through the Astaro to the Netgear and back out.
I would like to know if the home users connecting with the Avaya phones will be in need of a home router or if they can plug into a switch and still connect to the vpn. In the ip phone, it has settings for the gateway, would i set this to there pcs gateway if they didn't have a router. It would be the ip of the ISP gateway? I have tried with a cable connection and just a switch and it doesn't even hit the Astaro box.
Also, would there be a way to share the remote users pc connection for the phone? New at VOIP, thanks for any help.
