Hello
i have a strange problem, with setup up ip aliases. My Network
looks like
INTERNET
|
CISCO-ROUTER
E0 E1
| |
--- FBSD1---
| |
| |
--- FBSD2---
|
- REALWEB
For failure case we setup two squid- Accelators to the
REALWEB Server. These are running on to FBSD1 und FBSD2
machines. There are no Routing-Protocols used. And all
traffic from the internet is coming and going over E1(Ethernet).
Defaultroute is set to E1(CISCO) ip. Now the problem if I switch
off the FBSD1 e.g. and clear the arp cache on the cisco-router
an setup up an ip-alias on FBSD2 with the adresse of FBSD1 than
erverything seems to be ok. But some site from the internet
could reach the FBSD1(ip) on FBSD2 and i see in "netstat -an"
on FBSD2 that the SITE send SYN Packet but FBSD2 didn't answer them.
I look on the network E1 with an protocolanalyser and saw
the SYN Packets from this specific addresses but FBSD2 didn't
send a answer. After something like a hour this symthom suddently
disappear an everythink is ok.
Any idea
Meno
