Hi, |

To all folks that use their gentoo linux PC as their internet |
| 4 |
router/gateway, don't upgrade your kernel to 3.14.1 or 3.14.2. |
| 5 |
|
| 6 |
These versions have a bug related to IP packet forwarding. Internet |
| 7 |
upload speed for the NAT clients gets extremely slow (in the order of |
| 8 |
10Kbps), which download speed remain unaffected. I have spent the entire |
| 9 |
weekend trying to debug the slow upload issue. I tried different NIC's, |
| 10 |
different cables, different clients etc, problem was still occurring. |
| 11 |
Upload/download from the Gentoo linux PC is fine, but any NAT client |
| 12 |
exhibits the slow upload speed problem. I also suspected that somehow |
| 13 |
the MSS clamping with iptables doesn't work, that wasn't the problem |
| 14 |
either, because even with all tables flushed and only IP MASQUERADING in |
| 15 |
place the problem was there. |

I finally found a bug report that explains the symtom: |

I then downgraded the kernel to 3.13.11, which fixed the problem. So, |
| 22 |
all of you guys using your Gentoo PC as your internet gateway, keep |
| 23 |
3.13.11 around for a while. |
