My current network setup is as follows
auto lo
iface lo inet loopback
dns-nameservers 8.8.8.8 8.8.4.4
auto eth0
iface eth0 inet static
address 104.244.72.242/32
gateway 107.189.30.113
pointopoint 107.189.30.113
netmask 255.255.255.255
I was having an issue before where ARP would end up connecting to 104.244.72.1 causing issues I fixed that by adding
net.ipv4.conf.all.arp_announce=1
net.ipv4.conf.all.arp_ignore=2
arp now connects/returns only to
Address HWtype HWaddress Flags Mask Iface
107.189.30.113 ether 00:16:cd:0b:1e:7c C eth0
107.189.30.1 ether 0c:81:26:30:b8:78 C eth0
However this is causing issues still. How can I get it to only connect to 107.189.30.113
To add this environment is from within a nested virtual machine Proxmox node network is as follows
auto lo
iface lo inet loopback
iface ens3 inet manual
auto vmbr0
iface vmbr0 inet static
address 107.189.30.113/24
gateway 107.189.30.1
bridge-ports ens3
bridge-stp off
bridge-fd 0
post-up ip route add 104.244.72.242/32 dev vmbr0
post-up echo 1 > /proc/sys/net/ipv4/ip_forward
post-up echo 1 > /proc/sys/net/ipv4/conf/all/proxy_arp
The host I am with does do MAC filtering. I am trying to next-hop the connection.
