L2TP over IPsec not working about softether-docker

[weidi]

Hi @starlessboi, can you share logs from the container, you can get them by docker logs container-name
Also is there any firewall or NAT gateway in between and are ports forwarded (UDP 500, 1701 and 4500)?

Hi
sure
this log is constantly showing in container log:
139954790386488:error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt:crypto/evp/evp_enc.c:610:
139954790386488:error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt:crypto/evp/evp_enc.c:610:

there is no nat or firewall..public ip is assigned to VM directly
i don't understand the last part... of forwarding
I'm using docker compose version with this config for ports:
ports:
- 53:53
- 444:443
- 992:992
- 1194:1194/udp
- 5555:5555
- 500:500/udp
- 4500:4500/udp
- 1701:1701/udp

should i do other things?
thank you for your time.

Looks like an issue with the openssl library used. What image tag did you use? Could you try with softethervpn/vpnserver:stable (just making it public) ;) BR Johannes Am Mo., 11. Juli 2022 um 11:53 Uhr schrieb Mohammad < ***@***.***>:

i'm using the image, acoording to repo docker compose file:
toprock/softether:latest

changed the image to the one you said...problem solved!
but the below logs appears in container logs..
sh: iptables: not found
sh: iptables: not found
sh: iptables: not found
sh: iptables: not found

installed iptables into container..then the errors gone
commands:
docker exec -it softether /bin/sh
apk add iptables

thanks again for your time , and great job

Good finding! This is just a "warning" but will implement it publicly.
