I have a similar problem.
[code]eirik@VyOS-VM-rt1# show nat
source {
rule 100 {
destination {
address 0.0.0.0/0
}
outbound-interface eth1
source {
address 10.99.6.0/27
}
translation {
address masquerade
}
}
}
[edit]
eirik@VyOS-VM-rt1# run show interfaces

This is what happens when i try to ping an outside address from the host 10.99.6.5:
Sometimes first it creates a correct entry in the NAT-table, but after a few seconds it’s destroyed and it creates an entry without translation.
