Why would you want to. Vines has not been supported for almost 2 years. There are few sites still using it. We've used it for several years but will be going to Exch and Linux systems next months.

FracT to FR
I have a satellite office I support. The problem is connectivity with local ISP over dialup. A solution appears to be to link this office with our Peoria office via, 56K fracT-1 through a router and pix. In Peroia I would then terminate in a wan card on the 2600 and route to our FR connection to Chicago. A number of techs have told me this is possible. However, I have Home Office techs telling me this won't work. Does anyone have experience that can guide me on this problem. Ultimately I need to have a reliable connection that is secure sans FR connection costs.

Re: [Re: FracT to FR]
Well, we're using FR for security reasons which is OK by me but extraordinarily expense. They have rejected my proposal as not being functional / possible or better yet not something they thought of first. I think a pix firewall to the router and thence the FR network would be more than secure for 4 hosts!

As2609
I have an AS2509 RAS that apparently has a problem. It seems every so often both my RAS modems make a connection but the authentication fails. However, if I reboot the 2509 then all is OK for some period of time. Are there any thoughts as to what might be causing this?

Re: [RE: As2609]
I think it is os 12.0. Authentication is RADIUS vis Vines. I can't answer about frequency yet. However, I've been 6 months and this problem has occured and been corrected the same way at least 4 times. Thanks for your assistance.

Re: [Re: Modem question]
Some additional information is required here. First, the maximum limit is 53K (US) imposed by the line voltage restriction place upon telcos in the U.S. The speed reported is for only the instant it was measured as the connection changes dynamically over lifetime of connection. There can be only one A-D conversion in the line which terminates at the telco switch with a trunk side T-1.
