I am trying to set up Golem to provide on their mainnet. I have Ubuntu 14.6 LTS.

I have successfully set up and run Golem in their testnet several months ago.

I am required to and I am forwarding ports 3282,40102,40103. I spoke to my ISP (Charter) and they tell me they are not blocking any ports.

I am running ssh server on port 22, so I believe them.

Yet Golem cannot communicate along its ports.

I don't know what the problem is, but one thing bothers me is that could my ports be intercepted once they reach my box?

lsmod

joe@joeslinux:~/golem$ lsmod | grep iptable
iptable_nat            16384  1
nf_nat_ipv4            16384  1 iptable_nat
iptable_filter         16384  1
ip_tables              24576  2 iptable_filter,iptable_nat
x_tables               40960  5 ip_tables,iptable_filter,ipt_MASQUERADE,xt_addrtype,xt_conntrack

here is iptables

joe@joeslinux:~/golem$ sudo iptables -L -n -v

I am worried that with the * on the in and out columns, my ports go to DOCKER before Golem can find them.

Here are more commands:

joe@joeslinux:~/golem$ lsof -ni tcp:3282
joe@joeslinux:~/golem$ lsof -ni tcp:40102
joe@joeslinux:~/golem$ lsof -ni tcp:40103

These commands returned nothing.

joe@joeslinux:~/golem$ netstat -nat | grep :3282
joe@joeslinux:~/golem$ netstat -nat | grep :40102
joe@joeslinux:~/golem$ netstat -nat | grep :40103

As did these.
