VPN' s and Telnet sessions

[#1]

Hi all, I' ve got a bit of a wird problem. I have two satellite offices, one with a Fortinet 50a, one with a netscreen 25. At head office we have a Fortinet 60. I have VPN tunnels created between the sites which work very well except for a telnet application we use to access a Compaq Alpha Server. This telnet link drops after 5 minutes, consistently. This sounds like a normal timeout, I accept that, however it has only occured with the introduction of the Fortinet VPN' s. We used to have a single netscreen to netscreen VPN which didn' t do drop the link so I' m sure the problem lies with the Fortinet VPN' s. I can' t find any timeout settings and am stumped. Any advice gratefully received. Thanks. Roland.

that' s a common problem, get a CLI acces and type: # set sys session port 23 timeout 1800 Now your telnet sessions will expire in 1800 secs. Default is 300 secs (here are your 5 mins). You can see defined sessions timeout with: # get sys sess

Thanks, I' ll try this.

after 5 minutes.. lol Yet another vicrim of the default session timeout By default, the FG has a session timeout of 300 seconds. Remembet set system session port xxxx timeout xxxxx then 7 days in seconds is the maximum there is also a setting to change the default session_ttl for all protocols (eg change THE default session_ttl). YOu can find advanced settings on the CLI manual. Have a look at it.

Thanks, but I guess you' re talking about the admin console session, which I' m quite happy on a 5min timeout via telnet. The actual problem is a remote telnet session to a Compaq Alpha Server over a VPN, which I think Alex Boulanger may have answered. I' ll give that a whirl and have a look at the CLI manual. Thanks for the response, though.

Both, Thanks for your assistance. It' s staying up a treat now. I do love hidden features.

How did you fix this issue? I am having the same issue myself with a VPN tunnel and a telnet program....any help with this would be greatly appreciated.

# set sys session port 23 timeout 28800 Will give you 8 hours of no timeout. It' s worked superbly since I implemented back on the 15th and I now have happy (well relatively) staff.

just have a look at the top of this page..
