TomatoUSB

Hello together,

regarding to this topic "http://tomatousb.org/forum/t-343529/inbound-qos-not-working-with-current-git-build" and the post from teddy_b that he is expermenting with fastnat, I would kindly ask if there is also any setting for fast nat inside toastman builds?

background information: I have a 12000Kb downstream line and want to use it, but only geht 60000-80000 Kb :(

I can use my full 22 mb/s line, what router have you got?

wnr3500l :)

ive got an asus n-16.
maybe that's why?
or maybe something is set up improperly.

hmm i have no idea if it is related to the hardware. but i dont think so, because with the original netgear firmware everything works fine… i got there around 114000 Kbit/s which is quite ok.

hardware specs:

Model FCC ID Platform & Frequency [MHz] RAM [MB] Flash [MB] Wireless NIC

WNR3500L PY308400093 Broadcom BCM4718A@480 64 8 Broadcom
RT-N16 MSQRTN16 Broadcom BCM4718@480 128 32 Broadcom

both have the same chip with 480 Mhz… ofc the n16 has 128 mb ram, but if I take a look into mine, it says that around 20 MB are free and 40 are used:

root@router:/# free
total used free shared buffers
Mem: 61956 41536 20420 0 856
-/+ buffers: 40680 21276
Swap: 131064 188 130876

To answer your original question, fast NAT is in Toastman's builds. See line 441:

http://repo.or.cz/w/tomato.git/blob/ff57a95e1db707a6d56f306af99320df09281d0f:/release/src-rt/linux/linux-2.6/config_base

You can also check the status in the following file within the router:

/proc/sys/net/ipv4/netfilter/ip_conntrack_fastnat

so, i dont think i have fastnat:

root@router:/# vat /proc/sys/net/ipv4/netfilter/ip_conntrack_
ip_conntrack_buckets ip_conntrack_max ip_conntrack_tcp_timeout_established ip_conntrack_tcp_timeout_time_wait
ip_conntrack_checksum ip_conntrack_tcp_be_liberal ip_conntrack_tcp_timeout_fin_wait ip_conntrack_udp_timeout
ip_conntrack_count ip_conntrack_tcp_loose ip_conntrack_tcp_timeout_last_ack ip_conntrack_udp_timeout_stream
ip_conntrack_generic_timeout ip_conntrack_tcp_max_retrans ip_conntrack_tcp_timeout_max_retrans
ip_conntrack_icmp_timeout ip_conntrack_tcp_timeout_close ip_conntrack_tcp_timeout_syn_recv
ip_conntrack_log_invalid ip_conntrack_tcp_timeout_close_wait ip_conntrack_tcp_timeout_syn_sent

no ip_conntrack_fastnat file is there :(

maybe i use some very old version? 1.28.7446 MIPSR2-Toastman K26 USB VPN Ext Build ?

Check the same line 441 on Toastman build 7446, fastnat is not enabled back then:

http://repo.or.cz/w/tomato.git/blob/989b51f32203264292ab25761ca8f19e377bfac9:/release/src-rt/linux/linux-2.6/config_base

oh ok, so which version should I use now to get fastnat? Just asking because to said "not enabled back then", which sounds like it is disabled now. if it is not enabled in the current release, might there be a way to have it back ?

I have just posted a newer version 7467 with many updates to the code by Teddy Bear.

Fast NAT has received some attention I see.

BCM fast NAT: fix MARK target, clean-up.

Commit 2de8d7252dfb25868df5fe954c064812c4efc33c broke MARK target
by not checking 'ct' for NULL.
This reverts changes to MARK and CONNMARK targets since enabling/
disabling fast NAT with QoS activated is now handled in userspace.

There is increased support and more builds for the Linksys E series routers. Several bugs appear to have been fixed.

I also tidied up the menus, and changed the limiter nvram variable names for consistency with Tomato.
