I have 3 server called Server-A, Server-B, Server-C
This are the IP: (for example)
Server-A (100.0.0.18/29)
Server-B (100.0.0.21/29)
Server-C (100.0.0.22/29)
in Server-A (100.0.0.18/29) I have two VM it called VM-1, VM-2
This are the IP:
VM-1 (100.0.0.19/29)
VM-2 (192.168.1.2/24)
My problem is:
1. The VM-1 and VM-2 can access the internet, but sometimes the VM-1 is timeout.
2. The VM-1 can't ping the Server-B or Server-C and vice versa.
This is the /etc/network/interfaces configuration:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 100.0.0.18
netmask 255.255.255.248
gateway 100.0.0.17
post-up echo 1 > /proc/sys/net/ipv4/conf/eth0/proxy_arp
iface eth1 inet manual
auto vmbr0
iface vmbr0 inet static
address 192.168.1.1
netmask 255.255.255.0
bridge_ports none
bridge_stp off
bridge_fd 0
post-up echo 1 > /proc/sys/net/ipv4/ip_forward
post-up iptables -t nat -A POSTROUTING -s 192.168.1.0/24 -o eth0 -j MASQUERADE
post-down iptables -t nat -D POSTROUTING -s 192.168.1.0/24 -o eth0 -j MASQUERADE
auto vmbr1
iface vmbr1 inet static
address 100.0.0.18
netmask 255.255.255.248
bridge_ports none
bridge_stp off
bridge_fd 0
up ip route add 100.0.0.19/32 dev vmbr1
How to make the VM-1 be able to ping from Server-B and Server-C and vice versa?
