24.7 Production Series / Re: My first OpenVPN, ipv6 issues

« on: September 05, 2024, 10:59:12 pm »

UPDATE: I was trying to test the connection from within the private network. I tried from outside, both smartphone and notebook connected flawlessly.

Not that it would be useful in any way (at least to me) but, out of curiosity, what should I change to make it work from the inside?

24.7 Production Series / My first OpenVPN, ipv6 issues

« on: September 05, 2024, 10:28:19 pm »

Hi all,

I'm configuring OpenVPN server on OPNSense, I already done it successfully on some linux machines some year back and now it is my first time on OPNSense.

Client connection hangs at:

Code: [Select]

2024-09-05 22:26:14: Valid endpoint found: XX.XX.XX.XX:1194:udp
2024-09-05 22:26:14: TCP/UDP: Preserving recently used remote address: [AF_INET]XX.XX.XX.XX:1194
2024-09-05 22:26:14: UDPv4 link local (bound): [AF_INET][undef]:0
2024-09-05 22:26:14: UDPv4 link remote: [AF_INET]XX.XX.XX.XX:1194
In the OpenVPN log I see the following error repeated every few seconds:

Code: [Select]

Connection Attempt write UDPv6: Can't assign requested address (fd=9,code=49)
It seems to be the same problem described here: https://www.reddit.com/r/OPNsenseFirewall/comments/1adzr5y/openvpn_setup_instances_getting_ipv6_address_error/
I tried to look for the setting to disable IPv6 in the Instance settings page but I can't find it.

What should I do?

Italian - Italiano / Ottimizzazione PPPoE WAN per FTTH 2.5gbps

« on: January 04, 2024, 11:33:10 am »

Ciao a tutti,

sono alla prima esperienza con OPNSense, ho un contratto fibra con TIM per FTTH a 2.5Gbps e un OPNSense installato su appliance con porte 2.5gbps.

La configurazione del PPPoE mi è sembrata molto semplice solo che non riesco a raggiungere la velocità sperata.

Da ifconfig vedo che sia la porta WAN (igc0) collegata all'ONT TIM che la porta LAN (igc3) collegata allo switch di casa hanno correttamente negoziato i profili 2500Base-T:

Code: [Select]

igc0: flags=8863<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=4802028<VLAN_MTU,JUMBO_MTU,WOL_MAGIC,NOMAP>
ether 00:e2:69:6b:61:1d
media: Ethernet autoselect (2500Base-T <full-duplex>)
status: active
nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
igc3: flags=8863<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
description: LAN (lan)
options=4802028<VLAN_MTU,JUMBO_MTU,WOL_MAGIC,NOMAP>
ether 00:e2:69:6b:61:20
inet 192.168.68.254 netmask 0xffffff00 broadcast 192.168.68.255
media: Ethernet autoselect (2500Base-T <full-duplex>)
status: active
nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
Se faccio uno speedtest (ho provato vari server) da OPNSense mi attesto sui 900Mbps, sulla rete ho alcuni PC gigabit che ottengono singolarmente dei risultati dalla speedtest simili a quelli del firewall, se lancio lo speedtest in contemporanea su piu' PC vedo che il traffico della WAN arriva ad un massimo di 1.20-1.22Gbps.

Lato TIM ho verificato che abbiano attivato il profilo corretto, intatti ho 930-950Mbps di upload.

Mi piacerebbe sfruttare a pieno i 2.5Gbps avete suggerimenti per test o tuning del profilo PPPoE?

Grazie
