Squid Proxy Transparent + OpenVPN + tcp_outgoing_address possible?

[crissi]

thx, i red the documentation about the templates several times, but to be honest for me are the steps absolute not clear yet..

Could you please explain detailed what you did?


Yes, such an important Feature like this, should be already available in the Gui, and not to screw around in the FW Files ..

Tested now further, and did the following @thefunkygibbonwith with your answer in the other post, dont know, if this is correct:

Code: [Select]

cd /usr/local/opnsense/service/templates/OPNsense/Proxy/

Created new File

Code: [Select]

nano customtcpoutgoing.conf

Added to the File tcp_outgoing_address 10.40.x.x

Then edit File +TARGETS File in the same Directory and added there 

Code: [Select]

customtcpoutgoing.conf:/usr/local/etc/squid/squid.conf

saved and restarted Squid

Then afterwards checking squid.conf

Code: [Select]

# tail /usr/local/etc/squid/squid.conf
tcp_outgoing_address 10.40.x.x

So the tcp_outgoing_address 10.40.x.x is set, but all other settings are overwritten...

Do i need to coppy all settings from squid.conf under /usr/local/opnsense/service/templates/OPNsense/Proxy/ to my created customtcpoutgoing.conf + tcp_outgoing_address 10.40.x.x

Thx!

honestly mate, I don't know any more.  i think we're both at a place where all we need to happen is to know the proper way of "adding" a line of config to the squid config using templates so that it doesn't overwrite all the other config and that it doesn't get lost in an upgrade.

its going to need someone that knows how to do this.  I don't see anything of the like mentioned in the opnsense documentation and I can't make head nor tail of the documentation for that template system.

yes, correct.. the topic here has 1500 Views already, but no one else way in here , and give us the last piece of the puzzle to move forward, this really sucks...

[thefunkygibbon]

just had some time to play again.  looks like the cron job set up to run the script isn't actually running it. can't see anything in my logs either.  ugh... on the verges of giving up

[crissi]

Hi,
same here, cron job isnt running, and nothing in the logs, executing the script manually works fine

Hope someone give us a hint?

[crissi]

temp working solution for me executing the script every minute

Code: [Select]

nano /etc/crontab -e


Code: [Select]

*/1 * * * * root /root/vpnscript.sh

For future references, there's an alternative approach here: https://forum.opnsense.org/index.php?topic=32642.0

Thanks, dont want to install squid on a other pc, to get this working...

I saw that someone else asked to implement this on Github https://github.com/opnsense/core/issues/5868 but the Issue timed out automatically, as now one seemed to pick the task, unfortunately...

Hi,

I'm struggeling with the tcp_outgoing_address parameter, i cant get it to work. I have a working wireguard (road worrior setup) connection and a working squid proxy but when I add the tcp_outgoing_address parameter all the connections through the proxy time out.
Do I need any new routes or fw-rules to get this working?
