With the recent news about TCP state manipulation I have found out I have an older Internet facing router that is vulnerable to attack.
Its a c2621 running:
IOS (tm) C2600 Software (C2600-IS4-M), Version 12.3(26), RELEASE SOFTWARE (fc2)
The router only has 16mb of flash and 64mb of main (RAM) memory.
The the patched IOSs all require 32mb of flash memory and 128mb of RAM.
What can I do today to workaround this obvious problem??
