Hi,

following problem:

pfSense:     R1   Router/FW between Lan L1 and Internet
LAN Router:  R2   Router/FW between Lan L1 and LAN L2

pfSense is default gw for all hosts in local LAN L1. pfSense has a
static routing to an internal Router R2 for a private LAN L2. SSH to a
host in the private LAN L2 from Linux in local LAN L1 is ok. SSH to a
host in the private LAN L2 from Windows is ok for only a few seconds,
after that, the connection hangs. Tcpdump on R1 further show packets
going to the Host in L2, but nothing comes back. R2 has a packet
filter, so maybe there's a problem. Ok, so far so bad.

I would suggest R1 to send redirects to the initiator of the connection,
but no ICMP redericts are sent from pfSense. Took a look at
net.inet.ip.redirect and found that it was set to "0" (interesting,
because net.inet6.ip6.redirect is set to "1"). Changing the value to
"1" doesn't change anything. No ICMP redirects are sent form pfSense.
So, is there any cause, pfSense doesn't send any ICMP redirects?

Anyone who want to help?

BR,
  PIT
