After deactivate network log :

Local network seems to work, but no external …

Hello!

While Eddie is not running can you please flush all the nft rules and check the DNS settings? To flush the rules:

sudo nft flush ruleset

Also check the remaining policy of INPUT and OUTPUT chains of the filter table (if existing) if the problem persists, just in case they are still set to 'drop'.

Kind regards

sudo nft flush ruleset

Same things

Also check the remaining policy of INPUT and OUTPUT chains of the filter table (if existing)

# nft list table filter
Error: No such file or directory
list table filter
           ^^^^^^

I set https://www.fdn.fr/actions/dns/ for DNS


But there are something strange

I look to resolv.conf : it stay eddie after deactivate it.
 

# cat /etc/resolv.conf 
#
# Created by Eddie. Do not edit.
#
# Your resolv.conf file is temporarily backed up in /etc/resolv.conf.eddievpn
# To restore your resolv.conf file you need to log in as root
# and execute the below command from the shell:
#
# mv /etc/resolv.conf.eddievpn /etc/resolv.conf
#
nameserver 10.128.0.1
nameserver fd7d:76ee:e68f:a993::1

the n i force to

# cat /etc/resolv.conf 
nameserver 80.67.169.12 
nameserver 2001:910:800::12

Deactivate/reactivate network : seems OK.

Question : why  my content will need to be approved by a moderator

After updating manually /etc/resolv.conf
Launch eddied and start VPN:

# cat /etc/resolv.conf
#
# Created by Eddie. Do not edit.
#
# Your resolv.conf file is temporarily backed up in /etc/resolv.conf.eddievpn
# To restore your resolv.conf file you need to log in as root
# and execute the below command from the shell:
#
# mv /etc/resolv.conf.eddievpn /etc/resolv.conf
#
nameserver 10.128.0.1
nameserver fd7d:76ee:e68f:a993::1

But, before i don't have /etc/resolv.conf.eddievpn
And now have it again …

Seems related to resolv.conf

Hello!

Yes, it looks like Eddie does not manage DNS properly. This thread is being sent to Eddie's developer.

Kind regards

Something that work :
1. Deactivate eddie and network lock
2. Create/fix your own  /etc/resolv.conf
3. test web : it's OK
4 activate eddie, check resolv : replaced
5. deactivate eddie : resolv.conf are replaced

I don't know when i loose my resolv.conf + it's not related to my network manager settings here …
