Edit ssl vpn server config file - remove server side disconnect timeout

Erik, is this a question about Remote Access or Site-to-Site?

Are you looking for /var/chroot-openvpn/etc/openvpn/openvpn.conf-default?

Once you solve this, please post the tricks back here.

Cheers - Bob

Remote Access.

Here is the content from /var/chroot-openvpn/etc/openvpn/openvpn.conf-default

dev tun
tun-ipv6

[<LISTEN>]
mark 4458

daemon
multihome
topology subnet
server [<SERVER_POOL>]
[<SERVER6_POOL>]

[<OPTIONS>]
cipher [<CIPHER>]
auth [<AUTH>]
comp-lzo [<DISABLE_COMP>]

persist-tun
reneg-sec [<RENEG_SEC>]
keepalive 10 120
verb [<DEBUG_LEVEL>]

capath /etc/openvpn/ca.d
cert /etc/openvpn/server.crt
key /etc/openvpn/server.key
dh /etc/openvpn/[<DH_FILE>]

client-config-dir /etc/openvpn/conf.d
status /var/run/openvpn-status.log
ifconfig-pool-persist /var/run/ipp.txt

management /var/run/openvpn_mgmt unix
management-client-user root
management-client-group root

plugin /usr/lib/openvpn/plugins/openvpn-plugin-utm.so

As I understand OpenVPN Keepalive 10 120 is the same as

ping 10
ping-exit  120

In order to change anything here, I believe I must either restart SSL VPN by doing a configuration change, like selecting another certificate or by reboot?

I'm not sure what you want to change to what now, Erik.  I thought you made changes to the SSL VPN Config File for the client.  To make that change in the default, that's a different location.

I want to achieve that the SSL remote access client do not disconnect during inactivity and I am curious about the server side configuration.

Last time it happened according to the log was a server side disconnect.
