I have the following setup XXXXXXXXXppp0 XXXXXXXXXXXXX X linux X----------------------------------X cisco 801 X XXXXXXXXX192.168.40.1 192.168.40.2XXXXXXXXXXXXX 192.168.1.164 192.168.5.1 The cisco dials into the linux box and the connection is very slow (for a dialup). If I ping cisco to linux it gives a 30% packet loss but linux to cisco gives no packet loss. Telnet linux to cisco is OK but telnet cisco to linux is very slow. I suspect routing but I can't see any problems. The same setup works perfectly on SCO 5.0.4 but I don't want to use it on that server. routing is setup with ip-up.local on the linux box Linux is redhat 7.1 with kernel-2.4.2-2 ppp-2.4.0-2 mgetty-1.1.25-5 netstat -rn on linux Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 192.168.40.2 0.0.0.0 255.255.255.255 UH 40 0 0 ppp0 192.168.5.0 192.168.40.2 255.255.255.0 UG 40 0 0 ppp0 192.168.1.0 0.0.0.0 255.255.255.0 U 40 0 0 eth0 127.0.0.0 0.0.0.0 255.0.0.0 U 40 0 0 lo 0.0.0.0 192.168.1.1 0.0.0.0 UG 40 0 0 eth0 show ip route on the cisco Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, * - candidate default U - per-user static route, o - ODR, P - periodic downloaded static route T - traffic engineered route Gateway of last resort is 192.168.40.1 to network 0.0.0.0 192.168.40.0/24 is variably subnetted, 2 subnets, 2 masks C 192.168.40.0/29 is directly connected, Dialer1 C 192.168.40.1/32 is directly connected, Dialer1 C 192.168.5.0/24 is directly connected, Ethernet0 S* 0.0.0.0/0 [1/0] via 192.168.40.1 Any suggestions as to where to start would be appreciated.
