CABLENUT and Internetsharing help

Post by DAVE »

i just reinstall my computer so i need a cable nut setting
my desktop running winXP pro
the laptop run win98SE
the ISP is rogers cable 1500/192
i used HUP and 2 NICS to share the internet
TCP options string = 020405b401010402

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.

Default Receive Window (RWIN) = 17520
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 17520
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)

bandwidth * delay product:
Your RcvWindow limits you to: 700.8 kbps (87.6 KBytes/s) @ 200ms
Your RcvWindow limits you to: 280.32 kbps (35.04 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.

MTU Discovery (RFC1191) = ON

Time to live left = 115 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

Hey DAVE, for the XP pc use the following settings:

DefaultReceiveWindow = 192512
DefaultSendWindow = 49152
DisableAddressSharing = 1
InitialLargeBufferCount = 100
InitialMediumBufferCount = 240
InitialSmallBufferCount = 320
LargeBufferSize = 81920
MaxFastTransmit = 64000
MediumBufferSize = 15040
PriorityBoost = 0
SmallBufferSize = 1280
TransmitWorker = 32
FastSendDatagramThreshold = 4096
EnableFastRouteLookup = 1
EnablePMTUDiscovery = 1
IgnorePushBitsOnReceive = 0
GlobalMaxTcpWindowSize = 64240
MaxFreeTcbs = 8000
MaxHashTableSize = 16384
MaxNormLookupMemory = 5000000
SackOpts = 1
SynAttackProtect = 1
Tcp1323Opts = 0
TcpLogLevel = 1
TcpMaxDupAcks = 2
TcpMaxHalfOpen = 100
TcpMaxHalfRetried = 80
TcpRecvSegmentSize = 1460
TcpSendSegmentSize = 1460
TcpTimedWaitDelay = 30
TcpUseRFC1122UrgentPointer = 0
TcpWindowSize = 64240
MaxConnectionsPer1_0Server = 20
MaxConnectionsPerServer = 10
DefaultTTL = 64
DisableUserTOSSetting = 0
TcpMaxDataRetransmissions = 6
DefaultTOSValue = 92

For the 98SE pc first install the vtcp 386 patch then use the following settings:

BcastNameQueryCount - 1
BcastQueryTimeout - 100
BSDUrgent - 1
CacheTimeout - 600000
DefaultRecvWindow - 64240
DefaultTTL - 64
EnableDNS - 0
GlobalMaxTcpWindoSize - 64240
KeepAliveInterval - 500
KeepAliveTime - 14400000
Lanabase - 0
LocalCopyMade - 1
MaxConnections - 64
MaxConnectRetries - 5
MaxDataRetries - 64
NameTableSize - 255
NameSrvQueryTimeout - 100
PMTUBlackHoleDetect - 0
PMTUDiscovery - 1
RoutingBufSize - 146432
RoutingPackets - 100
SackOpts - 1
SessionKeepAlive - 7200
SessionTableSize - 255
Size/Small/Medium/Large - 3
Tcp1323Opts - 0
TcpTimedWaitDelay - 30
MaxDupAcks - 2
DefaultTOS - 92
IGMPLevel - 2
MaxConnectionsPer1_0Server - 20
MaxConnectionsPerServer - 10

For both pc's do the following:

1. Open IE and select tools - internet options - connections - LAN settings, make sure NOTHING there is checked.

2. Make sure you have the latest drivers for your NIC from the manufacturer. Set your NIC duplex mode to 10mb half duplex for Cable, for DSL it is ISP dependent unless you are using a router, if so then set it to 100mb full duplex for both Cable & DSL (the instructions are in my Help & Tips link).

3. Clear your temporary internet files.

4. Power cycle your modem, unplug it for atleast 15 seconds.

5. Download and update then do a scan with SpyBot, anything checked in red is spyware and safe to remove.

Also if I remember correctly your caps should be 1500/384 let me know if that's right or wrong. :D ;)

the speed of internet sharing between a router and a hub which one is faster
i used a hub for a long time and i think that's enough and i don't need to change to a router
my Laptop only use for chatting and my desktop on 24/24
