hi group,
I report that I currently have problems with the synchronization of mail with an outlook client with a gmail account with a domain, through Roadwarrior VPN.
I have something like this:
It is important to mention that I have a server with centos 8 and virtualized this nethserver with two network cards (red and green) and I have doubts if the centos shorewall is the one who is preventing access.
Hi @Steven_Pazmino,
welcome to NethServer Community.
Which Outlook version do you use and is there an error message from Outlook?
Do you use Proxy/Web Filter or IPS?
Does it work without VPN or if you disable “Route all client traffic through VPN”?
You may check /var/log/firewall.log or stop the shorewall with
shorewall clear
to check if it’s preventing access.
Restart firewall after testing:
signal-event firewall-adjust
Are there errors in the logfiles like /var/log/messages or Outlook:
BTW, you may check out the new server manager.
The client is Microsoft Outlook 2016
The message is as follows:
I use transparent proxy:
Does it work without VPN or if you disable “Route all client traffic through VPN”?:
Correct, it works without vpn.
Correct, it works when deactivating Route all client traffic through VPN
The downside is that if I disable this option: Route all client traffic through VPN
I lose my connection to the sql server and the only way to have the connection is to activate it.
Are you able to ping imap.gmail.com from the Outlook client when you are in the VPN? Is DNS working?
Is the SQL server in another network? Maybe you just need a route?
Is it pingable from VPN? What if you use IP instead of name?
If I ping and tracert with the vpn above:
In the nethserver rules I have the following:
The sql server is on an ip of the company’s LAN network. For this, I enabled a rule in the shorewall to allow me to enter port 1433 and in the nethserver I have no rule since the ones I created did not give me access to the sql server.
These are the ports that I have enabled in centos 8 shorewall:
Is it pingable from VPN?
I can ping and remote desktop with vpn upstairs from my home to the company lan network
What if you use IP instead of name?
use ip where ???
It is worth mentioning that when I am not connected with the vpn if I load outlook with the gmail account
Good afternoon,
I still have the problem, suddenly something else that I should try?
I solved the problem, configure the Centos 8 shorewall firewall (rules file) in order to direct all traffic from it to Nethserver. Once this is done, the Nethserver firewall rules are carried out to allow the necessary accesses.
it doesn work yet, my friend.
