WTF!?

Tried to dump all iptables rules. No luck =(((

logger "Setting default filter policy"
iptables -P INPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -P OUTPUT ACCEPT
logger "Flushing all rules"
#-F flushes all the chains. Chains can't be deleted unless they are empty
iptables -F
#-X Delets all the non-builtin chains in the table
iptables -X
#-Z Zero's the packet and byte counters in all chains
iptables -Z

1. try to change localhost by 127.0.0.1

2. Do you run rsub on local or remote host?

3. does something listening on 52698 on your local machine?
   probably port is forwarded but nothing is listening on your local machine

run sudo netstat -tulpan | grep 52698 ( or at least netstat -an| grep 52698 ) on local and remote host.
