Hmm, but SNAT happens in POSTROUTING.
Where can we enter routing path after bridge went though postrouting...?
Normally if bridge packet has local dst mac kb traversal is:
bridge prerouting -> bridge input -> ipv4 prerouting (hook invocation
suppressed via bridge netfilter sabotage hook)
Depending on route table we then end up in ipv4 input (again suppressed)
or in forward and postrouting.
What is the issue, exactly?
