19.1 Legacy Series / nginx reverse proxy IPv6 --> IPv4

« on: May 04, 2019, 05:33:55 pm »

Hello,

can I use nginx plugin as reverse proxy from IPv6 address to internal server with IPv4 address only?

With all I tried so I do not get it running.

My starting point is that my IPv4 setup is running: WAN IPv4 --> nginx --> DMZ IPv4
I set-up IPv6 GIF tunnel (HE) and in firewall I allow on tunnel interface ICMP and port 80 and 443 to "this firewall'.
No further set-up of IPv6 address to any other interface.
When I look on sockets bindings of nginx to ports looks OK for IPv6:
  www  nginx  tcp6   *:443   *:*
  root   nginx  tcp6    *:80    *:*
  root   nginx  tcp6    *:443    *:*
Ping from outside to local GIF address is working fine.

But http and https access from outside to local GIF address timed out. Nothing I can see in the firewall logs.

Any idea what to do?
Or is it simple not possible what I want to do?

19.1 Legacy Series / performasnce issue with McAfee endpoint security?

« on: February 09, 2019, 03:05:16 pm »

Hello,

I noticed a strange behavior with the combination OPNsense 19.1, Windows 10 , McAfee Endpoint Security 10.5. Connection to WAN hangs dramatically (PING as well download speed).

I moved in a new home, got a new PC and updated to OPNsense V19.1 at the same time. All internet devices are running perfectly with the Netgear router from internet company. But wenn I echange the Netgear router with my OPNsense box the Win PC internet hangs, both over LAN and WLAN while iPhone, iPad and Android phones are running fine with OPNsense box. LAN connecton from PC to OPNSense box seems to work without problem.

When I disable McAfee endpoint security on the Win PC it also runs fine with PFsense.

Any idea where the incompatibility between OPNsense and the PC can come from?

I am pretty sure that there is nothing wrong with the PC setup as it is a standard configuration of a big corporate running on thousands of PCs in the same configuration.

18.7 Legacy Series / igb NIC - WAN drop and increased PING time

« on: August 12, 2018, 03:31:51 pm »

Hello,

With OPNsense 18.7 I still have the issues on WAN port with increased PING time till packets lost and drop of WAN connection. The issue is a know issue related to igb driver or Intel NIC. In my case it is an Intel NIC i211-AT on a Qotom Q335G4. I see the issue only on WAN port that is connected to the cable modem AVM Fritz!Box 6490. On LAN ports connected to a Cisco switch all is fine (I always can reach OPNsense Web interface via these LAN ports). My first supect was the modem. But after this was getting exchanged the issue still is there.

The issue also is reported on pfsense forum and in this old post here
https://forum.opnsense.org/index.php?topic=5511.msg28687#msg28687

I tried out all recommended tuning parameters, but all without success. I believe I see an improvement but no solution.


/boot/loader.conf.local

Code: [Select]

kern.cam.boot_delay=10000
kern.ipc.nmbclusters=1000000
hw.igb.num_queues=1
legal.intel_ipw.license_ack=1
legal.intel_iwi.license_ack=1
hw.pci.enable_msix=0
hw.igb.enable_msix=0

in optimizatino parameters

Code: [Select]

dev.igb.0.eee_disabled=1
dev.igb.1.eee_disabled=1
dev.igb.2.eee_disabled=1
dev.igb.3.eee_disabled=1

Is there anyboy working on this topic?
Is there already a solution that helps?

Thank you

« on: July 31, 2018, 10:05:20 pm »

I just updated to 18.7. But now I cannot login any more with root and my local password. It is getting rejected with "wrong password". 


Network connection to internet is working. Servers on VLAN connection via HAproxy I also cannot reach.

18.1 Legacy Series / bind routed IPv6 subnet to services

« on: March 31, 2018, 12:58:35 pm »

Hello,

is it possible to bind services from OPNsense to IPv6 address of a routed subnet?
Specifically, I am interested in HAProxy.

So far my OPNsense up is working fine. I have IPv4 WAN via PPPoP and IPv6 via a GIF tunnel with routed /48 subnet. Routing and filtering of IPv6 to the different internal networks with /64 subnets out of routed /48 subnet is working fine.

I have set up HAProxy as reverse proxy for several web services running behind OPNsense. With IPv4 this is working fine. With the IPv6 endpoint address of the tunnel it also would work.

But is it also possible to bind HAproxy to one or more IPv6 addresses of the routed IPv6 subnet instead of GIF tunnel endpoint address?

This would allow me proper DNS entries incl. PTR matching to the several domain names used.

Thank you.

Hardware and Performance / SOHO hardware MINISYS

« on: March 18, 2018, 09:16:36 pm »

Hello,

currently my OPNsense is running under Hyper-V. But I am planning to move it to a dedicated hardware.

Qotom is the company some are recommending also for pfsense. Qotom Q355G4 has CPU from Broadwell generation. The MINISYS IBOX-501 N13 has Kaby Lake CPU generation.

I am not familiar nowadays anymore with this big variety of different CPU types for mobile, embedded, desktop and server. Is here anybody with experience of different CPUs in combination with OPNsense?

Is there any significant difference in power and power consumption between Core i5-5250U of Qotom Q355G4 and Celeron 3865u and Core i3 7100u of MINISYS IBOX-501 N13?

Thanks.

18.1 Legacy Series / VPN road worrier IKEv2 and DNS for local domain not working

« on: March 18, 2018, 07:49:56 pm »

Hello,

I finally could set-up road worrier VPN with IKEv2 to work with iPhone (iOS). On OPNsense "Mutual RSA" and on iPhone cert-based authentication was the only IKEv2 based combination I could get running. Firewall setting and access to OPNsense ubound is set-up and seems to me correct by now. (IPSEC is in virtual network 192.168.200.0/24 and LAN is 192.168.100.0/24)

Everything so far works fine except of DNS for local network. In "mobile clients" of IPSEC settings in OPNsense the local DNS server 192.168.100.1 is set-up. By using a network tool on iPhone I can get DNS resolution for clients on LAN from DNS server of OPNsense on 192.168.100.1. But by using standard without giving explicit DNS name the iPhone is not contacting the local DNS for local domain.

Configuration issue or bug on OPNsense or on iPhone with iOS 11?

Thank you.
