Methods of programatically altering ipsec rules with C#?

由 冷暖自知 提交于 2019-12-20 03:13:52
问题 The only method I know how to execute IPsec changes involves calling netsh to do the changes. Is there a method using System.Management and WMI objects directly? If so, what is it? I am having a hard time finding relevant WMI information with MSDN. Or is there some other useful method someone out there has used? EDIT: I am working in C#, and would prefer C# examples with regard to .NET System.Management based answers. Thank you! 回答1: 1) Exact: WMI. The EnableIPFilterSec WMI class static

Proxmox with OPNsense as pci-passthrough setup used as Firewall/Router/IPsec/PrivateLAN/MultipleExtIPs

由 纵饮孤独 提交于 2019-12-14 03:24:54
问题 This setup should be based on a proxmox, being behind a opnsense VM hosted on the Proxmox itself which will protect proxmox, offer a firewall, a privat LAN and DHCP/DNS to the VMs and offer a IPsec connection into the LAN to access all VMs/Proxmox which are not NATed. The server is the typical Hetzner Server, so only on NIC but multiple IPs or/subnets on this NIC. Proxmox Server with 1 NIC(eth0) 3 Public 1IPs, IP2/3 are routed by MAC in the datacenter (to eth0) eth0 is PCI-Passthroughed to

How to extend VpnService to open an L2TP/IPSEC connection in android programmatically?

由 非 Y 不嫁゛ 提交于 2019-12-13 15:23:38
问题 I am looking to implement a solution to open a L2TP/IPSEC connection from the android application so I can simply pass the server ip , pre-shared key , username and password and so the device is connected to this VPN server I looked here https://developer.android.com/reference/android/net/VpnService.html that we need to extend and build our own VPN solutions to do that. Is there any available solutions for that so we can use it instead of reinventing the wheel? I tried the below

问题 I install the module scapy for python 2.6 and when I import this module I get this warning: WARNING: can't import layer ipsec: 'module' object has no attribute 'IPPROTO_AH' I looked in the socket attributes and i didnt find the 'IPPROTO_AH' attribute In addition, i tried to edit the module ipsec.py and find way to replace IPPROTO_AH with something else but then i got WARNING WITH IPPROTO_ESP ! I tried edit lines in ipsec.py such as: overload_fields = { IP: {'proto': IPTest}, IPv6: {'nh':

IKEv2 Rekeying of IKE_SA using CREATE_CHILD_SA message

由 和自甴很熟 提交于 2019-12-07 22:06:06
问题 I have a Confusion regarding rekeying Procedure of IKE_SA in IKEv2. MY confusion is when rekeying of IKE_SA is done whether its repective Keys of CHILD_SAs ie. ESP or AH SAs would be change or not. As per rfc 7296, in rekeying procedure of IKE_SA new SKEYSEED would be generate and then new set of {SK_d | SK_ai | SK_ar | SK_ei | SK_er | SK_pi | SK_pr} = prf+ (SKEYSEED, Ni | Nr | SPIi | SPIr). i.e. new Sk_d is generated.So, using these new values whether new keymat would be generated or not by
