|
# have CONFIG_IP_NF_TARGET_TCPMSS set.
|
|
#
|
|
# [From the kernel help:
|
|
#
|
|
# This option adds a `TCPMSS' target, which allows you to alter the

|
# MSS value of TCP SYN packets, to control the maximum size for that
|
|
# connection (usually limiting it to your outgoing interface's MTU
|
|
# minus 40).
|

#
|
|
# This is used to overcome criminally braindead ISPs or servers which

|
# block ICMP Fragmentation Needed packets. The symptoms of this

|
# problem are that everything works fine from your Linux

|
# firewall/router, but machines behind it can never exchange large
|
|
# packets:
|
|
# 1) Web browsers connect, then hang with no data received.
|

# 2) Small mail works fine, but large emails hang.
