### Description

I've got a 2 node private network with `Node 1` designated as bootstrap node. After the nodes are up and running, I upload a text file using the web UI on `Node 1` and I can `ipfs cat QmcD4SAMXhr4Upko9eC5XKDuGYyP2Q4GRYindJEE3qmesH` the content on `Node 1`, but the same command hangs on `Node 2`.

When checking the output of `ipfs stats`, we observed that:

* DHT queries appear to be working on both nodes and reflect responses from the other node:

```
## Node 2

ipfs stats dht

DHT wan (0 peers):
DHT lan (1 peers):
Bucket 0 (0 peers) - refreshed 7s ago:
Peer last useful last queried Agent Version

Bucket 1 (1 peers) - refreshed 2m40s ago:
Peer last useful last queried Agent Version
@ QmWwaegHzNhBewhj97fbZdSrcT6YXuq2wEwAorrhnWi4T9 7s ago 7s ago go-ipfs/0.9.1/dc2715a

## Node 1

ipfs stats dht

DHT wan (0 peers):
DHT lan (1 peers):
Bucket 0 (0 peers) - refreshed 3m3s ago:
Peer last useful last queried Agent Version

Bucket 1 (1 peers) - refreshed 3m3s ago:
Peer last useful last queried Agent Version
@ QmPaCd2ckD9ffRwTzmQJNrGQS8J6JoAHvyP1MsWSCdcaqn 1m10s ago 24s ago go-ipfs/0.9.1/dc2715a
```

* Bitswap stats show that `Node 2` lists **0 partners** and `Node 1` lists **1 partner**

```
### Node 1

bitswap status
provides buffer: 0 / 256
blocks received: 0
blocks sent: 0
data received: 0
data sent: 0
dup blocks received: 0
dup data received: 0
wantlist [0 keys]
partners [1]

### Node 2

bitswap status
provides buffer: 0 / 256
blocks received: 0
blocks sent: 0
data received: 0
data sent: 0
dup blocks received: 0
dup data received: 0
wantlist [0 keys]
partners [0]
```

* We tried to execute `ipfs bitswap reprovide` on `Node 1` but that did not help.
